Mathcad

I have an old file that colleagues developed and they created variables like this: Rop%.  I'm trying to re-create and improve some plots, which use this variable, among other similar definitions.  When I retype the variable name, Mathcad tells me the variable is invalid; undefined.  For the life of me, I can't figure out why.  But it looks like the percent signs (%) have different fonts.  So it looks like there's something different about them, but I can't replicate it.  Please see attached.   

Does anyone know how to reduce the file size of a MCP sheet or other ways to speed up processing? I am working on a big calculation package that reads in Excel data (~30000x15) and manipulates it various times (loads of filtering, sorting, assigning submatrices, etc.) that is going on 20-30 pages. Now the file size is almost 18mb and the sheet is moving very slow and takes a while to save. TOL and CTOL are set to defaults, and I am trying the multithreading option. Only working on one sheet at a time. Are there any methods to speed things up? Maybe purge past data once a step has been made? I don't have much experience with the clear() function, but could this be of use here? Open for suggestions. Thanks!MCP 8.0, Windows 10 Pro.  

I am trying to install a temporary mathcad prime free trial and I am not sure how to install the temporary license.  Any instructions that can be provided will be greatly appreciated. Thanks.   

Hello.I received an activation code from my university to install MathCad Prime 6.0.I can't find where to download it.I read that it is no longer available and the licences are transferred to Prime 7.0, but maybe i understood wrong.Please help me.thank you.

I am trying to download my licensed issue of Mathcad . Clicking 'download' link takes me to the page to select the version I want. The only version available is PTC mathcad Prime 8.0 Student Edition - datecode 8-0-0-0 - which then states is 'unavailable'........ Thank you.

Hello, I need to have a conversation with support, licensing for ths product seems to be a joke and I am having issues. Brand new customer, just purchased the software.  no phone numbers for support is such a pain.      

We received an email inquiry which I had forwarded to a Mathcad product manager. I thought it may be useful for others, too, so instead of just emailing the response to the customer, I am posting it here as well.   ------- We need to convert .mcd to .mcdx...We have Prime 6.0.0.0What do we need and how much does the program cost to do this conversion. ------- The .mcdx file format is Mathcad Prime. The .mcd file format is for earlier versions of the legacy software, later versions of the legacy software use the .xmcd file format.   If this customer uses Mathcad Prime 6.0 there is a converter that comes with the software they can use to convert all .xmcd and most .mcd files to .mcdx - ‘most’ .mcd as we only go back as far as something like legacy Mathcad 7, which was late 90’s I think.   From the Input/Output tab in Mathcad Prime 6.0 they can find an ‘xmcd/mcd converter’ button - clicking that will open the converter. They will need the latest version of Mathcad 15.0 (M050

 Hi! I surprisingly found that Mathcad calculates this simple expression wrong:  Both results must be the same. The second result is the correct one.It gets even worse in this case:  It seems that Mathcad accumulates floating point errors in sums, which can be easily avoided (or greatly reduced) by applying a proper summation algorithm. It costs nothing to implement, so why not do it?

Hello,   Unfortunately, since a new installation, it is no longer possible for me to set a valid license.dat. The present files end with the note that they are not valid. I only get a timeout error over the Internet with a user and password. What can I do to activate Mathcad 14. Thank you in advance for your efforts!   Best regards Udo Wilczek   Google translate Translated by - Anurag Singh Date - 02/24/2023     Hallo, leider ist es mir seit einer Neuinstallation nicht mehr möglich eine gültige license.dat  einzustellen. Die vorliegenden Dateien enden mit dem Hinweis, dass sie nicht gültig sind. Übers Internet mit User und Kennwort  erhalte ich nur einen Timeout-Fehler. Was kann ich machen, um Mathcad 14 zu aktivieren. Vielen Dank im Voraus für Ihre Bemühungen! Mit freundlichen Grüßen Udo Wilczek          

Does anyone know how to speed up MCP for processing large data sets? I am working with a 50832x14 size data set that is output in Excel from another program. I would prefer to filter, sort, and manipulate the data in MCP vs Excel. However, trying to execute a simple filter step in MCP on a data set this large has proven impossible. I can't get the function to complete (endless spinning wheel). Whereas I can complete this one step in Excel in about 1sec. Does anyone know how to speed this up? Or any other tricks for processing large data sets in MCP? I would really, really prefer to avoid Excel but at this point I have to use it. Thanks! 

I want to construct a program in such a manner that both the variables are unknown and whole number a+b=5a is a whole numberb is a whole numberb>aCould you please help?

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 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

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.
