Mathcad

I am hoping you can help. As you can see below, I would like B17 to be 32.95, as if B15 is 0.005 and above, it should round up. And if it is 0.004 and below, it should round down. you can

What does a vector mean in MathCad? I often get the same error but in different functions 

Hi there,  we have so many inputs I need to write a program to tell mathcad , if the input matrix or table has less than 700 rows don't include it in the calculation. Can you help me doing this , please? The sheet is attached . For example I don't want Mathcad to do the calculation for CPT3 because it has less rows than 700 

I'd like to check a simple-span beam for the effects of a torsion load along the beam span. This requires some element-wise operations as well as a function for angle of rotation. Attached is the portion of the sheet where I'm running into a vector/scalar error. I'm running Prime version 7.0. I'd like for the output to include the first, second and third derivatives of the angle of rotation at 3 points along the beam span (the load point in addition to both ends of the beam). Is there a good way to manipulate the matrix setup or include the derivative functions within the main function in order to produce an output?

I want to use equation C in next way:i=number of A membersPerform C with first member of B and the whole vector A until i+1st member of A becomes lower than i-th member of A. After that, perform C with next B member and continue with A until the same thing appears. In the end I wish C in the form of matrix which will include every calculation which should be 4x4 matrix. Thank you!

I have created the below set of equations, however the solution for the definite integral should be Joules, not Watts. I have shown a solution for QdotDOOR to show that I am getting the correct units at that point. Can anyone advise where I have gone wrong? For reference, I am trying to find the heat transfer through a door over a 15 minute duration.

Hi,I took one of the equation from this topic https://community.ptc.com/t5/Mathcad/Newton-s-method/m-p/949155#M211771  I see that Solve Block does not give all the solutions of the system equations only by trying only one pairs of (x,y) guess values: And we need to change manually the guess values in the hoping that we will get the all solutions. But what to do when we do not have other alternatives to know that the system of eq has more one solution and when with the limited guess values tried we got the same solution? But my questions are:1. Why Solve block gives solutions like x=-0.779 and y=-0.443, why other method gives x=-0.22, y=-0.69, and so on.2. How one can be sure while using Solve Block he finds all the solutions of when solving the system of equations? As I do not like the solution given with solve block that we cannot be sure that we found all the solutions, as one cannot be sure that he tried all the variants for guess values.Without changing the guess values

Dear Mathcad community, I am writing my first post on this forum in the hope that someone can assist me with a question. Firstly, I would like to say that I am using Mathcad Prime 9.0.0.0. and I am attempting to multiply two matrices and I am struggling to achieve my objective. I want to multiply matrix A (with i rows and j columns) by matrix B (with j rows and 1 column), in order to obtain matrix C as shown in the image (with i rows and j columns). Subsequently, I aim to determine the maximum value of each row in C later. Thank you very much in advance for your assistance. Sincerely, Germán. 

Hello,I don't know why, but mathcad prime 8 don't open the attached file. "The file type is not supported. ..." If someone could help restore the file, I'd greatly appreciate it. Bence

Hello My friend send me files that are made by new version of mathcad and I still have mathcad 7 prime trial version, how could I open these files or should I try to get them as pdf then? Best regards Jarmo

Can someone solve this for Mathcad 15?

I need to install my (very old) Mathcad v14 onto a new PC. I need a license file for it. The "Mathcad License Setup" wizard fails to retrieve a license over the internet. How can I get a license for this old product?

Hi all,The advanced controls are a dream come true for me, but has probably opened up a rabbit hole of documentation. I added a textbox with the intent that users could enter dimensional strings in a user-friendly format like:10'-2 3/8"and the output would be an inches value of122.375 I'm having two issues, first being the output is a string "122.375" and not a numerical value, and ideally the value would actually be defined with MathCAD's units: 122.375*inAny assistance on how to get this working would be appreciatedfunction TextBoxEvent_Start(Inputs, Outputs) { // TODO: Add your code here }; function TextBoxEvent_Exec(Inputs, Outputs) { var input = TextBox.Text(); // Get the input value from the first input var inches = parseDimension(input); // Convert the dimensional string to inches Outputs[0].Value = inches.toFixed(3); // Output the value in decimal inches to 3 figures }; function parseDimension(dim) { var parts = dim.split("-"); // Split the string by feet and i

In another post I asked a feedback about the development of Matchad Prime (MCP) v.10 as compared to the previous versions.  Up to now I kept my Mathcad (MC) 11  - the first "love" in this field of software - despite the problems of running it in the new OSes. Apparently its seems that MCP is not near (for a general math user) after 10 versions to what it was MC 10, i.e. Mathcad 2001i (the preceeding version of MC11). I was also told to give a try to MapleFlow (MF), given the fact that also MC11 hides a maple symbolic engine. So I did in a backup computer with v.2023.3 - the latest. As already observed several features of MC are absent in MF. For instance it does not have a alignment option of formulas, as MC11 does (see picture). Moreover, I did not find a list of functions, that are instead directly accessable in MC11. At the same time, MF shows a feature that I greatly miss in MC 11: a list of assigned variables in the worksheet. I guess also its symbolic engine i

Hi experts, newbie here. Is there a way for me to program this, where when f(x) changes sign, it automatically stops solving. Thank you so much, any help would be greatly appreciated. 

Hello,I have these points: How to calculate each colored area from below plot made with above points?   Mathcad Prime 9 fille attached.

I am using Mathcad Prime Release 9.0 and Datecode9.0.0.0We have three older Mathcad files that Mathcad 9 is not able to convert for some reason.We receive the message "Conversion failed. Unexpected error encountered during conversion." We are then provided with incomprehensible text files describing the issue.Can someone try converting our files for us?

Have dual loads of P9 and P10.  My application is CPU intensive.  Recent testing showed a big difference so I did a simple sum test.  The results are not good in my opinion.  Can this be fixed with a patch?  Bloatware at its finest - added functionality with engine overhead.  

Can anyone here tell me why I can not plot the X-Y Point from that DATA TABLE?

Hican anyone here explain, why I get this error`? 

Dear all,long time ago after I did programming MathCAD.How can I filtering on DATA Matrix here for all submatrixes which have conc = 0.5 f.e.I did this but is buggy. Maybe some one can tell me, so that I can remember my knowledge Ihave forgotten. thanks

I have downloaded a trial edition of MathCAD prime 10. However it has defaulted to an express account and cannot use the prime features during the period. How is this resolved?

Engineer here, I need help understanding the limits of my approach. I have a fairly simple electrical circuit, which I can solve very easily by hand - there is only one voltage source which is in series with 3 impedances, and then two external impedance branches.  BUT, I want to simply write the various equations and solve them in an AX=b approach. With the specific impedance values you see above, this approach fails. A is singular, and using lsolve(A,b) in Mathcad reports, "the calculation is not converging".  If I change the bottom left impedance from j1.224 to j1.2 and change the one directly above it from j1.224 to j1.5 I get a solution. But, the lsolve solution differs from inv(A) times b solution and both are wrong.  The current leaving the + terminal of the source will be -j0.30 A by my hand calculation. I've attached a pdf explaining my circuit and a Prime 9.0 file with my simple calculations (I can provide an 8.0 if needed). I'm sure it just
