Mathcad

Hi, I have problem with step range function when I put step which gives me array with more than 5000 elements. It gives me an error with overflowing. It is really strange for me because when I insert an array with more than 5000 elements from excel table, it works fine. So, do you know why this is happening, because 5000 elements doesn't sound too big for me. If it's overflowing, do you know other way how I can make an array with size of inserted array from excel, because it is important for me that number of elements of array can vary with using other excel tables. Thanks in advance and Best Regards!

hi I'm in charge of application support.  How do you generate a mathcad usage report?  i would like to see a list of machine names/usernames/ datetimes and license number to see who is using what version and when?  I have tried doing this through the ptc community website it all it gives me is the license and subscription information.  not the detailed users who are checking out the licenses.  thanks  

I used below to command promt.but still in solidworks mathcad addin not showing.May i know is there any further steps there "C:\Windows\Microsoft.NET\Framework64\v4.0.30319\regasm.exe" /codebase "C:\Program Files\SOLIDWORKS Corp\SOLIDWORKS\Ptc.MathcadPrime.Automation.dll" /regfile:myRegistry.reg version: Mathcad prime 8 and solidworks 2020 

Please advise how to get rid of the little green box around letters and symbols in worksheet and make them not printable.it's annoying me. Thanks, Ruoshi 

 

 Could someone explain, please, how possible to build two or more curves at one graph (plot) in MathCAD Prime? "This variable is undefined. Check that the label is set correctly." the error message is shown.

Just started to use MathCAD Prime v8.0 (before were using MathCAD 15). Is it correct, that if variable has a subcript, then the "Find" function for this variable does not work?Just if it true, it does not make sence to use this software -> because user cannot trace the path of this variable in the entire document. 

How to implement the frequency response calculation and graphic plot of Fourier Transform and Laplace Transform in our Mathcad tool  ?  Need  sample file for example with explanation!   Thanks in advanced! Evan 

I have a problem with the eigenvals() function. USALLY the results are sorted from largest to smallest, but occasionally they will be out of order. I have found the following simple matrix that demonstrates this:[A] = 1.0053 1.0053 1.0053 1.0053 2.0001 2.0001 1.0053 2.0001 3.4365 eigenvals(A) = {5.301 0.337 0.803}This can be a tremendous problem if, for example, I have a 100x100 matrix and I only need the first 3 eigenvalues and their associated eigenvectors.See attached mathcad sheet with demo and illustration of what I go through to sort the values and vectors properly. Surely there must be a better way!

Hello, I would like to solve an equation containing vectors (the result is also a vector) using programming. I tried using the solve block as indicated in the attached file, but I don't obtain the expected results (see Case 2). The expected result should be equal to the "y" vector from Case 1 highlighted in grey. Am I using the Solve block incorrectly? Is it possible to create a program for this situation (proffered solution).I am using Mathcad Prime 8. Thank you,Otilia

Hello All.   This question explicitly is addressing Mathcad PRIME (Current Version 8).  Not Mathcad 15. Is there a workaround on how to "easily" employ the Del Operators such as gradient, curl, and divergence in Mathcad Prime.  We can do it "long-hand," but not like what we had with Mathcad 15, so the Mathcad Prime presentation of the equation is more intuitive to students and closer to what we write on the chalkboard.  I can roll with the use of the Einsteinian Notation or Vector/Del or even just plain grad(), curl(), Div() notation. Cheers and Thanks.Bill CapehartSD Mines

As per the original post.    Can someone help me to convert this file in mathcad 2020(mcdx)?

Hello all, I have been working on this project to evaluate Weight as a function of Pressure, however, I haven't made much progress as I continuously get the error [Replace complex values and NaNs with real numbers]. I've been using Mathcad as a means to avoid coding but at this rate I may need to. Best, Cruz J.

Hello guys, I am new to this forum and this is my first post. I would appreciate input from others regarding my problem. Maybe I did a stupid mistake so please excuse that. In the picture you can see that I assigned all the Units regarding my Problem that I want to solve for, but nevertheless, mathcad tells me they are not compatible.   

I can hardly believe that I did not ran into this bug in the past. Or maybe I am blind and doing something wrong? Why is the horizontal base line if the second triangle not drawn in the combined plot? IMHO it should work (and I hesitate to say so, but it actually works OK in Prime). Has anybody already experienced that bug? Has anybody an explanation (other than "buggy programmed" 🙂 Has anybody an idea for a workaround? I thought that using complex numbers may be a way to get what I want, but, alas, to no avail! BTW, the problem goes away if the tringles don't share the common point (1;1). More precise: The problem seems to be that the last point of the first triangle is the very same as the first point of the second one. Sure in this simple example the order of the points could be changed to circumvent the problem, but in an automatically created list of a larger number of different shapes this seems not to be an inviting option. Any ideas are welcome. Mathcad 15 file attached &nb

I am trying to create a template for my company using Mathcad Prime 7.0.In the template I need to create excel parts in order to reproduce some tables. I have used the command insert object. The problem that I am facing is that the resolution in the final document once saved in pdf is not great, I should say it is quite poor. In addition, if I close the excel file and I open it again to add additional parts once close it doesn’t show the new parts in the Mathcad page. Is there a way to solve these issues?

I find very good puzzle from YouTube and show it. Then I made new puzzle to find the number of rectangles of stair-like figures shown here. How to calculate the total number of rectangles included in this figure? I have no formula to calculate this answer, now. First one, m=3 has 11 rectangles. Second one, m=5 may have 54 rectangles. How about m=7 and m=9?

I have an equation that has 3 real, numerical solutions. I'd like to have the symbolic solutions for the values of wo which are positive. I think the symbolic expression i'm after is actually only the 2nd numerical solution 0.4897... Mathcad finds a symbolic solution, but I don't know how to interpret the result or to use it. Worksheet attached... Many thanks for any help!

I am getting again the same problem where in it states the units are not compatible 

Hi, I have created some scripts to change some inputs in Mathcad and read the Output fields but I am finding troubles as the file is not fully updated when I read the outputs. I am trying to calculate with Syncronize() but overwrite my inputs and I would like to save the file but I am not finding the way. Thank you

I am a student and have already used the 30 days of trial for Prime 8.0 I need to convert a template from my professor that is an .xmcd file.  I cant convert it because I do not have the full version and I am not about to spend $60 to convert one file.  Can you guys help me get this file converted so that I can open it on Prime 8.0 please>

In an equation, the horizontal line between a numerator and a denominator is called the vinculum. In working my analysis using Mathcad Express V8, in some defined variables, the vinculum is greyed out while the rest is normal.  Another defined variable right above it is normal. The font type, size, and color are both the same.

Hi, People here on the forum helped me define a PWM controller, in the past. I made a tweak to that formula, so that it starts at zero. However, I've noticed there is a weird issue with Mathcad. If you look at two cycles, it will be off when it should still be on. This happens on the second cycle. It turns off one time step too soon. However, it's random and depends on the duty cycle entered. I'm wondering if there is another way to define this, so that this issue can be avoided. I've messed around with it as much as I can but have reached a dead end. Thanks, Anthony

Why we have not in Prime this unit as energy and temperature unit? The inventor of Mathcad - the nuclear physicist Allen Razdow would also be unhappy with this. SMath has!
