Mathcad

Does anyone know anything about Allan Razdow - one of the creators of Mathcad? I used to communicate with him both by mail and on Facebook, I wanted to invite him to Moscow for a conference. And now nothing is heard about him. It worries me.I visited him in Boston two time. He showed me the house where MathSoft was located. He told me a lot about this Mathcad and why it fell into the greedy hands of PTC. Mathcad was the only favorite son in the MathSoft household and became one of the stepsons in the PTC household. Alen's parents (Razdovich) emigrated from Yugoslavia to the United States before the WW2, where Alen graduated from MTI.By the way, the creator of the PTC is also from Europe - from Leningrad. In general, all the creators of the most popular CAD trinity (Creo, Autocad, SolidWorks) come from the USSR. This is not a brain drain - this is a transplant of brains into more fertile soil.

Is there a way? Possibly through an intermediate format via export-then-import process?

Hi!I have written som output in the excel component, and I would like to define a few values as "NaN" (they are out side my range of interest), but the excel component does not appear to accept NaN from excel. Are there any workarounds? Thank you! (using MC P7) 

Hello,  I can´t figure out by myself the syntax to pass a matrix from excel via SetMatrixValue to Mathcad Prime 7.I was able to write a single variable with "Call WS.SetRealValue("test", 6, "")" with no Problem but I can´t get it working with a matrix. The code I use: Dim MCPath As StringDim path As String path = Ordnerpfad(ActiveWorkbook.Path)MCPath = path & "\Rechenkern\....... Set MC = CreateObject("MathcadPrime.Application") 'CreateObject("Ptc_MathcadPrime_Automation.Application")MC.Visible = TrueMC.ActivateSet WS = MC.Open(MCPath)Call WS.SetRealValue("test", 6, "")Call WS.SetMatrixValue("test2", ?????, "") The variable "test" and matrix "test2" already exist as inputparameters in Mathcad, I simply want to change the value of the matrix like I did with "test". I hope somebody can help me with my problem. 

HiI would like to use simple "if" operators in my computation, just because I'm used to do so with Mathcad 15.Is it so that I also need to use "also if" statements with Prime?In some of my computations simple "if" statements appear to work, but for some reason the attached computations result into different results.Could someone clarify why I cannot use only "if" statements? Thanks

Hello everyone: This thread is a continuation (and different question) resulting from this thread: https://community.ptc.com/t5/PTC-Mathcad/Mathcad-Prime-Breaks-in-Integral-Graph-Causing-Problems/td-p/755864 The replies in that thread were helpful. However, I still have to take the integral of Werner_E's equation to get the moment graph; and now, I'm trying to take the integral again to get the deflection graph. Is anyone here good enough at taking integrals that you could provide formulas for the integral (as opposed to just using the software to taking the integral) and second integral of the equation in Werner_E's more efficient function V formula? For convenience, here is a link to his formula: https://community.ptc.com/t5/image/serverpage/image-id/48045iEF9ADF38676B3B81/image-dimensions/752x76?v=v2 Thanks in advance. 

Hello,i bought the prime 5 student version and in the installer i cant install the applicationwhat can i do ? 

Whilst playing around with a Newton-Raphson solver for a simultaneous set of functions, I noted a disparity between the Mathcad 15 and Mathcad Prime 7 results for the Jacobian of one set of functions.  To eliminate the possibility of other parts of the worksheet contaminating the environment, I copied the function to a blank worksheet.   Unfortunately, I get the same results.      Why is the derivative d/dξ for just cos(x₀) yet isn't when multiplied by x₀??     Mathcad 15 returns the result I expect.   Does this happen in Mathcad Prime 6 under the legacy symbolic engine? Is there a valid reason why this MP7 behaviour occurs? If so, should it? If not, is it a bug?   Stuart

Hello everyone, I am working on a specific case and I have a problem writing the correct code. Let me explain it.The file is attached. Even though some parameters are red, they are all known. I just had too much data to include in the file, and I just wanted to keep it simple. My goal is to obtain n1,n2,n3,n4,n5 coefficients, along with T1new, such that f(T) for this T1new will be equal to zero. Moreover, f1,f2,f3,f4,f5 must be equal to zero as well. As a result, I want to achieve such n1-n5 and T1new, that f1-f5 will be zero and f(T1new) will be zero. All other parameters are known. I am not even sure if I am on the right track to find the solution.Any help would be appreciated. RegardsMurarz  

Hello. I am trying install PTC Mathcad Prime Tryal version for 30 days but i am not being successful.

Hi all,I've a question regarding the use of the ODESOLVE function.In the attached file, I solve a ODE with the ODESOLVE function. It did work before, but now I changed 2 paramterers: How it was, and when ODESOLVE did work. How it is now. I've changed all the formulaes which include PB(rb,HL) too. But now ODESOLVE isn't able to solve the system. What could be the problem? Thank you lots for your help in advance!

Hi, guys,I am a teacher and would like to install MathCAD by usind an education license (which one don't need to pay).I alreadx created an ptc-account, but still can not find out, how to get an education license.

Can't get WRITEBIN to output to a subfolder in Prime 7.0, although other write functions such as WRITETEXT will. Does anyone have a workaround for this, or is this something Prime will support in the future?

Hello, I have a problem with my file and I don't know how to solve it. It should be pretty simple, but I don't know how to solve it. I'm including the files and my program. My question is as follows. In the first for (counter j), when it starts from zero to 3, it gives me some values, when I start from 3 to 3, it gives me another value. Somebody can help me?Thanks

Hello everyone!In-depth study of the propagation of the electromagnetic field in a rectangular section metal hollow waveguide, with a Mathcad 15 worksheet. Please report any errors. The animation could not be made. Hope the zip file is accessible.Greetings

Ich habe die "PTC Mathcad Prime 5.0 Student Edition - One Year Term License" gekauft und anschließend den Installationsassistenten heruntergeladen und gestartet. Ich konnte den Lizenzvertrag akzeptieren und auf weiter klicken, auf der nächsten Seite "Anwendungsauswahl" erscheinen in der Liste jedoch keine Programme, die ich auswählen kann. Eine Installation von Mathcad Prime 5.0 ist daher nicht möglich.   ----------------------------------------------------------------------------------------------------------------------------------------------------- I purchased the PTC Mathcad Prime 5.0 Student Edition - One Year Term License and then downloaded and started the installation wizard. I was able to accept the license agreement and click on next, but on the next page "Application selection" there are no programs in the list that I can select. It is therefore not possible to install Mathcad Prime 5.0.   Translated with Google TranslateTranslated by Anurag Singh, Jan 10th, 2022

Hi!,Basically I have to draw the surface distribution given by the function f (y, z) on the plane of the tube section whose position on the axis is changed by moving the cursor of the slider. The fact is that unexplained phenomena occur when the cursor is moved, such as enlargement or shrinkage of the tube. Is anyone able to put order into that program? I solved a similar problem for a community member about ten years ago or more, without the use of createmesh but only with programming. I can not find it anymore.

Hi, is it possible to use Mathcad for optical ray tracing? I am able to do the ABCD gaussian beam propagation but wish to visualise the rays i.e. bouncing off mirrors.I am running Mathcad 15Thanks

i want to check this out, seems pretty fun to begin

I am still using MC 14.0. I had to re-install it because the motherboard on my computer went bad. Now, when I go to the Trace tab in plot format it comes up blank and clicking on anything but cancel crashes the program. Other tabs are fine. I installed the M020 release but that did not help. Any suggestions?
