Mathcad

I am having trouble getting the 30-day license to activate. Every time I try to load the get license part of the wizard it fails and tells me to check the website which didn't help. If you could help me get the license activated that would be great. Thank you for your time.

Hello,  i have a Belgium azerty keyboard and several shortcuts don't work. how can i change the shotcuts to resemble my keyboard?I assume that in the 10 years knowing about this problem it has been fixed! It has already been reported in 2011. I read Italian and German has the same problem. https://community.ptc.com/t5/PTC-Mathcad/Mathcad-prime-1-0-bug-with-keyboard-shortcuts-with-Italian/m-p/291809  

This PTC Mathcad Prime 9 worksheet uses a simple physics problem to provide introductory information on some important fundamentals of Mathcad. The principles covered in this worksheet are at the core of using Mathcad, and should be helpful for those who are new to Mathcad and just getting started. Please note that this is not intended to be an in-depth tutorial, and therefore won't provide details on every mouse click and keyboard entry. There are tutorials available in the Getting Started tab on the ribbon, so if you find yourself needing a little extra explanation, the tutorials would be a good resource. 

I'm relatively new to Mathcad but I enjoy the program very much and I need some help. I would like to program the following section but I have no idea where to begin.   Your help will be appreciated. Regards,

Hey there, I am attaching the screenshot of an error that Math cad prime shows. Can anyone tell in detail what does that error mean? It says "this function requires at least 3 arguments but is applied to 2"  

Fourier analysis. For those interested in the subject, I propose forty-one periodic functions.  

Hello I'm new to Mathcad and have just taken over a file from someone at work. It runs fine but I am stuck manually copy pasting the results into an excel sheet. I want to automate the process and have tried using the WRITEEXCEL function but I can't seem to get it to work. See attached photo.   I believe it has something to do with the function qp(z) not being a matrix or array but I'm not sure. I've also tried defining M:=qp(z) and using M in the WRITEEXCEL function but that gave me a "variable is not defined error".

I am working on a calculation sheet to design a bridge deck overhang.  The last check I need to do is to calculate the cutoff length of the supplemental bars that are used.  In order to do this, you need to solve/find the location where the applied moments become less than the moment resistance of the overhang without the supplemental bars. The only way I can think to achieve this is to use a solve block, however, this becomes a problem if/when the applied moments are less than moment resistance at the cutoff location.  See the images below. For this example the variable Mr_co is the moment resistance at the cut-off location.  I have set up functions to calculate the ultimate strength moments for 2 different cases. As you can see by the graph, the ultimate strength moment for the one case does not quite reach the cut-off moment resistance.  I would like to set up the solve block so that if/when this happens, the return is 0, but I am not sure if this is possib

I am using Mathcad Prime 7.0 7.0.0.0I have a curve generated using a trace that connects plotted x,y points. How can I use Mathcad to calculated the area under that curve?

Hello everyone!I was not sure which topic to put this in, but I am trying to define my own units. This is a unit of cost per mass in analysing freight rates. i.e. My desired unit is to measure freight in £ per tonne. Is this possible?ThanksAndy

I finded the answer for the exercise but I don't know how plot a 3D for the solid of revolution of answer.

I've noticed that several posts have recently been unavailable when I've tried to access them by following a link in my email notifications.   Not being able to see them, I have had no idea why the posts were removed.   However, the most recent moved the post linked below to RemovedContent and I have no idea why an old post with a handful of responses has suddenly become a target for moderation.      The post asked if there were any ways to convert Mathcad to some standard programming language.  The action seemed to have been triggered by somebody posting a link to a Mathcad-to-C# converter.   Removal seems an overly heavy-handed action to me.      Several of us have looked at and manipulated the structure of Mathcad worksheets for a variety of reasons, including, but not limited to: worksheet repair, worksheet automation and expression-to-readable-equation conversion.    All, as far as I'm concerned, legitimate

Have been using Matlab and Mathcad since the 80's.   If I pull up a bit of 1980's Matlab code and try to run it, Matlab identifies the obsolete entries, I tweak them and it runs in a few minutes.   Mathcad has no backward compatibility.  As an instructor, it is unusable for class.  Users of different versions can't share files.  University has a license,  I have a license.  Students down load a trial version. Different versions. It is miserable.  It hurts my street cred with students that I use it.   I tell the students that since at least 2008 Mathcad has made using the software a hardship.     The best I have seen in put is that buying "prime is like buying the tail to get the dog".  PTC's solution is to kill the dog?   Duly noted that this has been remarked on for decades and usually more articulately than I have done here.  Just reminding PTC this is an acute pain point.

Hi, I am very new to mathcad, and am wondering if anyone could help me solve why when using Prime 7's inbuilt xmcd converter, the output of my for loop is no longer a matrix for all values of k, but the output for the final number of k only. I have tried re-writing the for-loop from scratch but that still gives me the same result.   Thanks in advance.

Hello   I used Mathcad 15. Due to termination of Mathcad 15 I am forced to switch to Prime. I used the internal conversion tool in Prime 7. The converter shows me several hundred conversion problems (converter is unsure if the conversion is correct...) Sometimes the conversion works. Sometimes not. Even if I converte the same file several times. I also observed the behavior that if I convert the same file multiple times I receive different conversion results.   Now I want to export my Mathcad15 in MathML. Not in simple HTML. I want a real MathML. I already exported the mathcad to HTML. But this export is .... "suboptimal". The formulas are exported as images. I can not copy them in a useful way.   --> Is there a way to export from Mathcad 15 into MathML? (Export from Prime in MathML is not suitable for me because the conversion into Prime does not work). --> Is there a plan/date when the converter (MC15->Prime) is fully functional?   Best regards   Mar

Hi, i need to convert my solution to MC prime 3.1 free. Would anybody help and convert it for me?

Hi, I am trying to optimize the solution of minimization function depending on the intial guess values. Surprisingly, my solutions are independent of initial guess values even though the function has several local minima. I am attaching the Mathcad 15 worksheet for the refrence. Any help will be highly appreciated!     Many thanks S

Can any of the "READ" functions in Mathcad Prime 7 import a text file to a vector of lines, whilst retaining all leading and trailing spaces?   I can easily write a short function using READBIN to get the job done, but I'd rather just use one of the READ functions.    Unfortunately,  I'm having a minor brain meltdown due to the extreme temperatures and humidity we're experiencing in my part of  Scotland (25 C and 64% RH), and I've gone option blind.   Everything I've tried ends up losing leading or trailing spaces.   Cheers,   Stuart

I'm making a thread calculator.  In order to check whether user input returns a 'typical/standard thread combination' or not (e.g. UNC, UNF, etc.), I want to have a master check list matrix, probably with a vhlookup. I'm lazy and don't feel like copying EACH element NaN...is there no way to select a bunch and copy it into the next row/column? I can copy multiple entries and paste a nested into one entry location, but not copy them over into multiple elements. I've seen a couple threads about using functions to make an empty matrix, but I can't quite figure it out...and really I'd probably want to make a filled matrix, and then manually edit some elements.

Does Mathcad Prime 7.0's Combo Box support units with exponents?  I am trying to enter steel properties in and when I type in^4 and in^3 that is exactly how it looks instead of in⁴ or in³.    

Hi, I am trying to find the local minimum of a function using Minimize function in Mathcad 15. I would like to use the Levenberg-Marquardt algorithm. However, I am unable to select this option from the menu, see the image below.  Please let me know if it is poosible with Minimize function.   Many thanks S  

I would like to convert my equations in a MathCad worksheet directly into a higher language (C or C++, or other) to run on a super computer.  Is there a software or second source software that can do this directly?

Does Express Prime 7 include the xmcd converter? I cannot access it.

Hi,   First post here. i am trying to compute the following equation but unsure of what the error message is meaning and how to rectify. I have included the equation from the Eurocode in the screen shot.   Any help is much appreciated. 

Mathcad Express Prime 3.1 program will not open. It worked when I first installed it but after a week or so, I tried to open it again and got an error message. When I hit, "OK" the message disappears. When I try to open the program, the program does not open and the message comes back. This just repeats and the program never opens. Here's the error message that pops up on the screen:An Unhandled exception occured on the dispatcher thread. SeeC:\Program Data\PTC\Mathcad Prime\Logs\MathcadPrime_Exception_20210712_100352.logfor more information. Prime will attempt to save any modified files andclose.Please restart the application. OK
