Mathcad

Do you know that trig functions have color QR codes - see picture and Mathcad files - 15 and Prime.

Is there a way to set up an auto save of the Prime 7 file while working on it, to prevent loss of work  in the event of a system computer problem.  This would aid in not having to re-create lost work.

HiI have attached 2 x CSV files and Mathcad Prime. I have isues on Page 5 of 9 calculation mean and SDThanks.

Which operator can I use in the equations for D, E, and F that can evaluate them the same way, except more efficient than how I have it shown (i.e. takes up less space on the page than both Methods)? (Yes, it took a long time to type them out. No, I'm not proud of my work 😅).I know I can simply define A, B, and C with more elements like I've shown in Method 2 to make D and E cleaner. But that still leaves the same expression for F in both Methods. The order of the elements in matrices D, E, or F isn't important for my application of this (it's for wind loading on roof parapets).Thank you in advance, and my apologies if this question has already been asked, or if it's excessively elementary! My grasp of matrices/vectors has always been poor, so I didn't even know what to search for. I tried a few key words, but alas, here we are.I'm using Prime 7.0 if that's important.

Dear colleagues! Please help me with the difficulties I am having trying to repeat a very important example step by step.I tried to do as much as possible myself.Nevertheless, a number of questions turned out to be impossible for me to handle.Since, apart from the context and previous calculations, the essence of the questions will not be clear, I am attaching the original MathCAD file, the PDF example file, as well as a .xls file for the calculations.All questions are highlighted in red in the MathCAD file with references to the example’s pages.I will be extremely grateful to everyone for any comments/advice/hints. P.S. I’ve tried to contact the author of this work in different ways, but there was no answer.

hi, I've forgotten how to work with data in classic mathcad. I have the questions in the file attached along with the data file. These are the three questions, for the sake of the post: 1) how to get x,y data into a function2) how to assign units to the data3) how to curve fit the data The questions would apply to any x,y data set. This happens to be a fan pq curve. Thanks, Anthony

Can i somehow round my answers with 15 units rounding rule with mathcad prime 7?What functions i have to use to do that if its able to do?

When I was 4 or 5 years old, I learned to count very quickly by... playing cards. See the picture and the Mathcad 15 sheet ib attach!    

Hi All,Is there any simple way that date in Mathcad Prime would be updated to current date. If it can be done with excel embedded can someone please share a example that would be much helpful. Cheers,Frank

How to update the date whenever the worksheet is opened? It should update the date as per current date. Is there any simple method to that. Can it be linked with excel without manually updating in excel sheet?  Cheers,Frank

Hi, can you help me please with this folder. I need convertion from mathcad 5 to mathcad prime 5.0.0. Thank you!

Hi everyone, Can someone convert me this file, please! Thank you! 

Hi, I'm trying to solve some ODE equations system to determine behavior of species, temperature and pressure for a plug flow reactor. I already put all equations, relations between all terms and also the initial conditions, but on odesolve block i receive a message that says: "Too few initial conditions". Thanks in advance for your help. 

Can we add subscript to subscript in Mathcad Prime? 

I am trying to create phasors as per :Synchronized sampling and phasor measurements for relaying and control - Power Delivery, IEEE Transactions on (tamu.edu)  (Pdf attached) Checking to see if my mathcad implementation is correct Thanks.   

Thanks.

Many years ago, I recall needing to install some SW (VB commondialogs or such?) in order to have real time active controls, e.g. scrollbars, function correctly in MCD11. If I documented this process, it appears to have been in write-only memory. I wasn't able to find the ancient references by searching here either. Anyone remember what needed to be installed, and the process? I seem to remember that RichardJ was a key resource at that time.Thanks,Lou

Dear Stuart or other power user,You mentioned that beside of mathcad you also experiment with maple. As I stick to real mathcad I would like to have a plan B for the moment my mathcad no longer works. So I am transferring some of my mathcad sheets into maple as exercise.In the attached worksheets I believe that I did exactly the same in both programs but the end result is 10 units lower in maple than in mathcad. I have tried to find the reason for days but was not able to pinpoint the issue. Would you be so kind to throw an eye on it? As the maple file could not be uploaded I provided it as a txt fileI already want to express my gratitude in advance for your help.Filip

can anyone please convert this file to latest mathcad prime supporting file

How can solve problem in attachment?

I would like to use genfit to fit a function with more than 9 parameters, and its not clear to me how to do that.  The web description page for genfit says: • vx, vy are vectors of real data values of the same length, corresponding to the x and y values in the data set. There must be at least as many data points as parameters.• vg is an n element vector of guess values for the parameters. If n = 1, then vg is a scalar.F(x, u) is a fitting function, or a vector of functions, where x is the independent variable and u is either a vector of parameters or individual parameter names. The following equation is both a valid representation for a fitting function:• n is a positive integer. In the case of non-vectorized parameters, there is a limit of nine individual names. For 9 or fewer parameters, just including the parameters in the fitting function definition as F(x, u1,u2,

I am using Mathcad Prime 7.0 7.0.0.0With an VisualBasic Programm we extract Calculations out of MathCAD 15.0into an Excel Table.I managed to transform the file from MathCAD 15.0 into MathCAD Prime 7.0but the extraction of the values does not work.I managed to open theI changed"GetValue" -> "InputGetValue"and"getelement" -> "GetMatrixElement"but the values still do not get transfered to Excel.What is the right syntax to adress the values in MathCAD Prime?(mcws stands for MathCAD-Worksheet)VB-Script-Line for MathCAD 15.0:Set MC = CreateObject("Mathcad.Application")Set mcws = MC.Worksheets.Open(pfad & Worksheets("Stammdaten").Range("MCDatei"))...WertEinlesenMCAD.uwrk = mcws.GetValue(varname).getelement(0, 0)Script for MathCAD Prime 7.0:Set MC = CreateObject("MathcadPrime.Application")MC.Visible = TrueMC.ActivateSet mcws = MC.Open(pfad & Worksheets("Stammdaten").Range("MCDatei"))....WertEinlesenMCAD.uwrk = mcws.InputGetValue(varname).GetMatrixElement(0, 0)

I am trying to achieve result with units however as soon as I input the units the answer changes Am I missing something
