Mathcad

Hi,I have this equation: I want to find time t (a symbolic expression for t) at which the above function is equal with 1. So:   What I am missing?  

Hi,   I am using Mathcad15 and new to it.   i need to feed typically 4 basic values into mathcad and get result back. i have more than 160 sheets to work.   Am trying to automate the values logged in excel to feed in Mathcad as different files saving as PDF well.   Can anyone suggest or confirm this one is workable.   I tried few times but end up with error loading page. Provided the code below.  

I am looking to do the following calc but I am getting frustrated with applying the correct units. I want the result to be in "pounds per gallon i.e. ppg or lb/gal".  Pressure is in psi, Depth is in ft, and the 0.052 is a conversion factor derived from converting the following:1 gallon = 231 cubic inches1 foot = 12 inches12/231 = 0.052 however i am finding it difficult to substitute the conversions into the formula. HELP!

I am using Mathcad Prime Release 8.0 and Datecode8.0.0.0How do you copy multiple math regions which are within a text box with intervening text to an area outside the text box. I wanted the copied regions to be separate math regions. The only way I found of doing this is to copy each math region separately. Is there a quicker way to do this?

Hello,Using this fit formula from below, how to determine a, b, c, d, e, and x coefficients in such a way to fit the below plot Flux Density vs Magnetizing Force: I think (but I do not know how to do) to read all the data points of each line (60uH, 40uH, 26uH) and then to make the curve fitting by using genfit Mathcad function, minerr or something like that.

Hello everyone,in the attached file below, fourth column of matrix I is d1 values.I want to loop through each d1 values and get R as a matrix.could someone help me hereattached mathcad 10 file.

As per the original post.    Hi   Two issues:  1. I would like to publish my chart in a journal paper but at the same time look nice on the work sheet. Through Chart component I can publish a pdf of a chart. Only pdf has good resolution (no matter how much you zoom the pdf, the resolution is great). But the other forms have poor resolution: jpg, jpeg, peng etc.    2. The Font size in the chart component window is fine but on the worksheet it becomes too small. If I make it bigger (in the chart component window) to look better on the worksheet, it becomes a bit too big for the Chart component. For example, a 10 point font on chart component looks much smaller on the worksheet chart.    3, Also, I would like to print multiple plots on one 8x10 page through the Chart Component. Is there a possibility to add multiple charts, give the page size etc in the Chart Component Window? I mean, in Matlab, we can use multiple charts in one shot. How do I do th

Are there available Control tools in MathCAD Prime 1.0, Same as MathCAD 15 has (Insert/ control/....)Thanks in advance for your help!

Hello,Using this fit formula from below, how to determine a, b and c coefficients in such a way to fit the below plot Core Loss vs Flux density: or   So, I think (but I do not know how to do) to read all the data points of each line (300kHz, 200kHz, etc) and then to make the curve fitting by using genfit Mathcad function, minerr or something like that.

Is there any way to move text around the sheet without it snapping to grid? I need to move some text in between two grids to put over an image. The lines of the image do not line up with the grid perfectly.

This issue continues the same problem I presented yesterday. This calculation was also easy to do in Mathcad 15, but I am having trouble getting it to work in Prime 10.I have marked the part of the calculation sheet that is not working in yellow.You can see that I calculated the normal to be cylinder using symbolic calculation and tried to use it afterward to calculate the magnitude of the normal vector to be used down the sheet to calculate the total current. However, now Prime 10 does not recognize the results of the symbolic calculation to obtain the magnitude of the normal vector. See the attached file. Thank you in advance, Rogelio

Hi - I have quite a number of mathCAD workbooks in a folder. To access them easily I set up an "Index" mathCAD workbook and typed out a list of them and had a hyperlink to each file so that I can open the index file and just click on the link to take me to the file. This was ok to begin with but if I move the folder then the links all need to be updated and there are quite a few of them now. I remember in the old version of MathCAD there was a way to make an electronic book and I think it worked if the folder with the electronic book was moved. Is there a way to make an e-book now or what is the best practice for this in MathCAD now. I' feel that this must be something that MathCAD users must still be doing but I can't figure out how. Any advice would be very much appreciated.

This is not a solution I was expecting am I doing something wrong ? I am using Mp9 Ivan

Hello to all,After converting a Mathcad 15 file to Prime 10, I encountered an issue with calculating the gradient of a vector function. While it works seamlessly in Mathcad 15, the same function does not yield the expected results in Mathcad Prime 10. Is there anyone familiar with this issue who can tell me what needs to be adjusted or modified in Mathcad Prime to make it work?I am attaching a file with the function and the gradient, as I converted it from Mathcad 15 to Prime 10. I really appreciate any help you can provide. Rogelio

I am suffering a similar (though much more repeatable issue).When we as a company upgraded to Prime I was the only one that could not use the symbolic engine & when I raised the issue it was fixed within 2 weeks. Since then I have had a laptop upgrade & it has reappeared.a repeat of the IT ticket has not resolved the issue. Even the simplest task causes the symbolic engine to crash: is the final response after many minutes of the sunflower twirling. Sheet is attached, but probably not helpful as I can give it to colleagues who don't get the same problem. For them it quickly returns the expected 4/9result. I keep harassing Martin the local IT guy, but all he can do is refer it up the chain & hits a wall. Any suggestions of things to try would be appreciated. ThanksAndy  (too)

Hi guys, can someone assist me with this one please? Seems like it should be fairly straightforward but it's got me stumped! A bit long-winded to explain so bare with me. I have data representing mass of concentric steel pipes and mass of the cement in the annuli of the pipes, bonding the pipes together, in separate arrays. The pipes/cement are long and get cut into manageable lengths. The columns in each array represent the remaining mass after each cut. The rows in each array represent each pipe or cement 'donut'. Hopefully this diagram helps, which is a cross-section through the pipes/cement, looking at one half only. The black bits are the pipes (3x), the orange is the cemented annuli (2x) and the red represents the interfaces between each pipe and the cement - 'cement bonds', of which there are 4:This is the array for the pipes (3 pipes, 6 cuts):This is the array for the cement (2 cemented annuli, 6 cuts):I have an array for the number of cement bonds:And an array for the num

Hello,Do any of you have a script for calculating a pseudoinverse matrix nxm?I found a script here, but it is written in Mathcad 15 and unfortunately I don't have a licence to convert it to prime. https://community.ptc.com/t5/Mathcad/Programming-example/td-p/229552  ThanksMichael

I am using Mathcad Prime Release 9.0 and Datecode9.0.0.0Trying to use basic ODE solvers like rkfixed within a solve block. My goal is to solve a pair of nonlinear ODEs (intial value problem) which are not linear in the highest derivative term, using state space if possible. I need to use the iterative solver block because reducing the ODEs to standard form is quite difficult. the odesolve function cannot handle these equations. Are the basic solvers usable in a solve block for this type of problem? If so, an example sheet would be very helpful, the documentation and forums have not been enough. I have begun trying to solve the simple spring/mass system this way, before tackling the full equations, but not yet successful.Here are the errors that I facedVariable undefined. Unable to form derivative matrix (odesolve).

Dear, I have a dataset where the first column represents the index of a vector and column 2,3 and 4 the three possibilities. The first row contains the classification for a specific condition. The dataset has been manipulated to align these indices and classifications. My vector, for example, have this format:: However, I'm having trouble getting the vertical-horizontal lookup (VHLOOKUP) to search for each element in my vector and correctly return the value at the intersection based on the classification assigned to each vector element. Anything I tried returned 3x1. I have tried it all from the similar post:https://community.ptc.com/t5/Mathcad/Use-vlookup-over-a-vector/td-p/482509 Prime 9 attached. 

In the attached MathCad worksheet is an embedded excel file that has VBA apps in it.  It takes data input and calculates to values C and C` or is suppose to.  The excel file "CANDCPRIME.XLS" on its own works fine but once it is inserted in to MathCad it is being blocked by Microsoft as "untrusted".  What do I have to do to make it run inside MathCad.  It use to just fine but I haven't used this MathCad worksheet for a few years because my work did not include a lot of steel design.  I am using a subscription to Microsoft Office 365 and have tried to modify all the security and "Trusted" stuff I could find to allow this to run.  And ass I mentioned above by itself runs perfectly. Put all the files attached in the same location.Any help is appreciated.  Thank you,John

Hello,  I am using mathcad prime 10.0 and have created a program to solve for F_rated. I then want reference this program in a for loop, however it says the inputs to the function must be integers. Outside the for loop the equation works fine so I am a bit confused.

Hi, I have a MC15 calculation-sheet of 200 pages that have been converted to Mathcad Prime 9.0 that runs extremely slowly and which im now looking to optimize. Changes in input that in MC15 would have taken 5-10 seconds to recalculate can now take upwards of 5 minutes or more before the sheet is updated. I've been trying to read up on ways to speed up processing in Mathcad Prime and have read that size of matrices, the use of If-statements and possibly the use of "strings" in aforementioned matrices may be culprits. Which optimizations do you believe would bring me the biggest improvements in calculation speed as opposed to how MC15 was working? Does anyone have any recommendations how i should go about rewriting If-statements? (see attached picture of an example) Im going to see if i can break up the sheet in parts and work on a part separately. Then i can also upload said part here for you to partake in. Kind regards,Johan

We bought Mathcad earlier this year.  I believe we bought it in February.  I have a new computer and just went to install it.  I downloaded and installed Mathcad Prime 10.  When we pointed to our license server, it doesn't work -- we only get Express functionality.  My IT guys think I need to download Mathcad Prime 9 and that the problem is that our license doesn't support 10.  That surprised me because we only bought it a couple of months before the update, but the message seems to indicate that could be the problem.  See below: 8/15/2024 10:49:42 PM : The license request failed.Requesting MathcadPrime ...7788@XXXlicense003: (-21) License file does not support this version. If I need to download 9, how do I do that? Or do we need a new license file on our server to reflect the update and allow 10 to work? Thanks
