Mathcad

Hello Dear Friends,1) How long or how many years from now do you think that Mathcad 15 (not Mathcad Prime) can still be used?2) And how long do you think that Mathcad Prime will outperform Mathcad 15 in terms of functionality and performance?Thank you.Best regards.

Does Prime 7 have the mathcad functionality: of check boxes etc as Mathcad 15?  

Been using express Version 4 for years. Trying to download version 7 never received e-mail with download instructions or the softwaregoran@forshager.comgoran forshagerForsHagerGroup

hi,   i'm still having problems trying to work with the output of the state space solver. it might be something simple, but i've been going in circles all day. the first problem is the plots look a lot closer than the table output. the second problem is there is a lot of error compared to the odesolve output. it's pretty easy to work with the odesolve output. the state space output has been giving me problems for days.   basically, i'm trying to compute velocity, acceleration, and kinetic energy from the state space output. the velocity doesn't match compared to what the solver outputs as the last column of the solution matrix. the acceleration doesn't seem to match either. i'm not sure why, when i plot it, it looks like it is matching. but if i look at the output in tables it's way off. i attached two files. the odesolve one seems to be fine. the state space file has been kicking my butt.   thanks,   anthony

Where exactly is this "Options list" ?    

Why is n taken as length(y)-1 rather than simply the length of y? In both Mathcad 15 and Prime 6, sometimes this seems to result in throwing away one observation. E.g., in the Prime 6 example, there are 12 observations, but only 11 show up on the plot.

Moving to Mathcad Prime is challenging Can someone help me with how to call excel data using drop down menus as we used to do in real Mathcad Also, can I make drop down menu reference excel data or to insert equations?

  Hello everybody. I have a problem for solving this equation in the first image using Math cad prime's solve block and the find function I have instead solutions this question mark. The 2nd image shows the solution of this exercise in Math cad 15; I am stuck trying to find the same solution as image 2 in Math cad prime. Thank you for your answers  

I am using Mathcad Prime 7.0 7.0.0.0I have a user that is having a strange issue where when she double clicks a Mathcad prime file a new instance of Mathcad opens for each file. I have already done a clean install of prime where I cleared the PTC folders from the computer and the registry. i had to do this because a few days after installing prime 7 it would not open at all on a couple of computers. After the clean install, this issue came up. I tried to replicate the issue on another computer by going through the same process but that computer works correctly. Any ideas?

Mathcad can't get the license. What do I need to do?19/04/2021 11:55:04 : The license request failed.Requesting MathcadPrime ...C:\Program Files\PTC\sw_license_email_5246793.dat: (-103) Cannot checkout an uncounted license within a Windows Terminal Services guest session.

I am facing a problem and can't figure out what is going on. I have seen previous posts on the community but not able to grasp the concept of vectors. Please, someone, explain the difference in clear terms so that nothing remains ambiguous. The first problem is I am trying to return two vectors in a 1x2 vector. This means it will be a nested vector. I have seen some posts where it is done but when I try to do it, it gives the dimension of a vector rather than the vector itself. Of course, the problems resolve when I use the augment command but I want to know why it is not printing the vector. In the below figure (obtain from the community) the D shows the vector elements but when I try to display it again, it display the size of the vector 😫 Similarly, the second problem is that when I try to plot vectors it says, "These array elements must be scalar. They cannot be vectors or matrices". But when I search the community there were examples where these plots were made. So, I am confuse

My MathCad document stopped working with this error message, and I cannot get it working again. I have attached the document here, and a picture of the error message. What can I do to make it work again?

For a project (designing a log splitter) at school I am now working with Mathcad for the first time. However, I am now running into some problems. Maybe it's something really silly but I can't manage to solve two unknown variables from two equations. On the internet it is done with the find() function, but for me it doesn't work. Each time the 'find' function will output the follow: Find(Ay, By) --> Find(Ay, By) where Ay and By are the unknown values.   If anyone knows how to do this, please let me know.   All variables and other text is in Dutch but this should not be a problem as it only concerns page 3.   thank you in advance!   Dennis,

Hello Everyone. From: Thanks in advance for your time and help. Best Regards.

hi,   i wanted to use a square wave to drive a mass spring damper system. i usually use the state space solver, as it has worked better than the other solvers. however, in this case, i get an error. note, the worksheet isn't fully setup yet, due to the error. i was trying to make an example, since there aren't any quick sheets for a square wave.   thanks,   anthony

Appreciate if anyone tells me what the code in the attached image mathematically means? Thanks in Advanced  

I've got problem with my free trial, in Mathcad License Setup, while login this alert comes up:"Section=ResponseHeader Detail=PO

I am using Mathcad Prime 7.0 7.0.0.0I can not find the installation for the Legacy Converter. It is not enabled in the Mathcad Prime program and when I run setup, I do not see the option to install it as described in the help website.Here are the errors that I faced None

we have mathcad 1988 version 2.0 which no longer support, these files are generated from same version in the year of 2007-08so now, i am not able to open those files with new version of mathcadany suggestions?

Hello,I am generating a MathcadPrime 3.1 document with c# using the interop "Ptc.MathcadPrime.Automation.dll".Everything works fine, but I like to save the worksheet as a pdf as well, I do not find the corresponding save as options, Mathcad 15  offered MCFileFormat.mcPDF format. Does something equivalen exist for MathCadPrime 3.1 .´Thank you in advanceJan

Hi all, in my first post, I've been pulling my hair out as to how to assign and format units correctly.   In the plot within the attached workbook, I would love the axis to be labelled (x)psi & (y)lbf, but I'm out of luck trying to get them there with the auto-formatting which mathcad employs.   Any hints would be gratefully received!   Thanks Andy

Hello,I want to create a square wave train with 40 kHz frequency. The problem with the attached worksheet is 1- it doesn't start from zero amplitude2- I don't know how to add the factor (x-vt) , x= position and v=the sound speed, to simulate the wave train propagation in "x" direction.Could you please give me some hints.All the best Payman

Hello Everyone. Thanks in advance for your time and help. Best Regards.
