Mathcad

HiI have plotted the results from two vectors. The graph resembles the shape of a half circle and I would like to find a function that fits the data so intersection points can be determined for other functions. I have tried many different curve-fitting tools but can't find a proper one that works.  I'm  thankful for any help!    

i have an older version of Mathcad (Mathcad 14). I have been using it for years. Prior to upgrading to Mathcad 14, I think I was using version 8. My old computer stopped working. Now I have a newer/replacement computer and I am trying to install my copy of Mathcad 14.0. I started the install process on my new computer. And it is asking for the version 8 product code. I looked but, I cannot find my version 8 disk or product code. Are you able to help me install my Mathcad version 14 on my new computer?I look forward to your response.Sincerely,YPM

Can I extract the values in excel component from graph plotted? Even the vector does not get correctly assigned to the function

Hello to everybody,after the last automatic Windows 11 update, when I try to make a 3D plot, the following error message appears (in Italian) "Eccezione generata dalla destinazione della chiamata", which in English, more or less, corresponds to "Exception generated by call destination".Probably, the Windows update has modified some files used by Mathcad 15 for creating 3D plots.Please, can someone help me to recover that Mathcad 15 feature?Thank you very much,Sarah

Occasionally, I'll insert a Visio object into MathCAD Prime (I'm using version 8) using copy/past (ctrl-c & ctrl-v).  This works and it's pretty much fine for most things - but I did notice the images look a tad fuzzy.    Is there anyway to improve upon this? It seems that copy/past from Visio to MathCAD Prime inserts an image into Prime - that is, the copied object is converted to an image upon pasting into Prime.  Is that correct?  If so, is there a way to increase the image resolution? I poked around attempting to insert an OLE object using Input/Output tab > Insert Object.  Maybe I don't know the best way to insert an OLE object - as my initial attempts were very sub-optimal - and difficult to work with compared to the simple action of copying and pasting objects. Any ideas? 

In earlier versions of Mathcad Prime, I could write the following expression:Simply put, I could define a variable symbolically and display the answer.  With the changes to the symbolic engine on Primate, this can no longer be done:This feature was great because I often used Mathcad during Engineering lectures to work examples problems.  My work around is:The first properly should use the symbolic equal to "=" and not the mathematical definition ":=" but it still works.  Anyone have any better suggestions or work arounds? Bob 

Hi I have purchased and have a valid license for Mathcad with order number : #1212582074439. Company name, Deepblue pvt. LTD. We have deleted the Mathcad in one system and now trying to reinstall the software which we could not able to install.We need a technical assistance for this.Thanks,Poovendan

Hi! I want Mathcad to give me the derivative of a function symbolically, but it doesn't work. Any suggestions? Using Mathcad Prime 7    

I have purchased the most recent Mathcad and it wants a verification code for my account.  Where is that? KJS

Conversion process comes with 'FAILED'       

PTC Mathcad Prime 8 has now released! @CatMcchad a quick interview with PTC Mathcad's product manager, @amcgough, for this blog article about what's new and exciting in Mathcad Prime 8, what new functionality users and veterans will look forward to using, and how the Mathcad team decides what new functionality to put into each release. Much of that is customer-driven, and Andy cited several delivered requests from the Mathcad Ideas board on this very community.Read the interview here:https://www.mathcad.com/en/blogs/why-prime8-andy-mcgough  Andy will also be available next week (March 22 at 10:00 Eastern) for a webinar about what's new in Mathcad Prime 8, featuring demos of the new functionality, plus a live Q&A portion with Andy that yours truly will be moderating. Register for that here (or catch the replay-on-demand after the fact):https://www.mathcad.com/en/resources/webcast/whats-new-mathcad-8 Happy calculating~

Hello, At that time I had bought a Mathcad license through the university. Now that I have a new PC and needed to re-download Mathcad, I was asked for a license key. I have also specified this, but it is shown to me that it is wrong. I hope you can help me there. Thanks very much!-------------------------------------------------------Translated the content from German to English language using google translate.

Da ich nun einen neuen PC habe und Mathcad neu herunterladen musste, wurde ich nach einem Lizenzschlüssel gefragt. Diesen habe ich auch angegeben, jedoch wird mir angezeigt dass er falsch ist. Ich hoffe Sie können mir da helfen.Vielen Dank!

A friendly hello to all,In the attached file from MC14 there are two solution blocks at the end for solving differential equations. So far I had to enter the same initial values in each solution block. Can these initial values be entered only once somewhere before for both solution blocks?Kind regards, Alfred Flasshaar

I am trying to get a speed unit (m/sec) into a combo box (prime 8.0.0.0), but this somehow does not work. I'm now using a work around first defining mps as m/sec then putting mps in the combo box. Same thing for accelerations (m/sec^2) Is prime still this much troubled by unit issues or is it just me having trouble coming from MC15. It appears to me such work arounds should have been implemented out of sight to the user by now. Celebrating 12 yrs of  PRIME (or mostly avoiding it for me to be just fair)  

I am a Mathcad user with a permanent license for Mathcad 15.1 and Mathcad Prime 3.1. On friday 17-2-2023 my model worked perfect in Mathcad 15.1. After running the model, windows updates KB5022497 en KB5022845 for  Windows 11.pro were run. From that moment on the import of files (text, Excel, dBase) were no longer working. The Windows updates therefore have been undone, but that did not solve the problem. Whether this is a Mathcad- or a Windowsproblem is not clear to me. Could anyw\one having faced this problem and resolved it post a message?   RE: post

I have an active license, but when i complete the install, my ptc desktop shows a "created with ptc mathcad express:" watermark..  Can you point me to the full installer or is there something i am missing with my install or my current license?  

to all, A question regarding the Cholesky LDL decomposition. given a matrix A one can have A=LDL* where L* is the transpose of L using the mathcad 15 cholesky(A), how does one code mathcad to get D? L = cholesky(A)   Thanks in advance Josh

New features for consideration:          

Hello,   How would you compare Mathcad with following software?   What would be the advantages of using Mathcad (Prime - because it was chosen to continue with MC Prime further)  compared to the following software: Standard Maple, Maple Flow, Wolfram Mathematica or Matlab? What would be the disadvantages of using Mathcad (Prime) compared to the following software: Standard Maple, Maple Flow, Wolfram Mathematica and Matlab? Why do you prefer Mathcad (Prime) instead of the other software: Standard Maple, Maple Flow, Wolfram Mathematica or Matlab? Or do you use the other software listed above besides Mathcad (Prime)? Why? Is it really better to use Mathcad (Prime) compared to the other software above, at least from the point of view of say the following fields: Engineering/Electrical Engineering, Control Systems, Signal Processing, Calculus, Matrices, Algorithm (convergence, accuracy, precision), working with units, programming? Is it worth messing aro

Hi, can someone help me by converting these old version of file (05 files) so I can open it in Mathcad Prime?  My option to convert the file is also grayed out. thanks!!  

Hello, How would one set limits for the variable in the solve command.  In the example below, I know that k has to be between certain values.Thanks,  

Does the mathcad subscription license (Prime8.0) support version 15? I can run Prime 8.0, but when I run version 15, I get a license error (-2, 15, 8, etc).   

Hallo you all, since a while i cant access Mathcad full version while beeing connected via public wifi. With my home Wifi it works fine.disconnecting VPN doesnt make a difference. Do you have any ideas whats the problem. Since working remote its kinda annoying. Thanks!!
