Mathcad

Can anyone recommend a good introductory text book for mathcad (I've got Mathcad15). I need something that covers the math operations, with plenty of fully explained examples (with keystrokes etc)? I use Mathcad as a math person (not an engineer). Many thanks. Peter Kirby.

Has anyone tried this... really important for school that's about to start :E I would like to keep using open source alternatives but I must make sure I can still learn like the rest at my schyool. Thank you!

Hello!I wonder if there is any way of plotting parametric curves where the parameter can't be  expressed in terms of variables ("x" and "y"). Example 1: Parametric curve x=t^3 - 4t,  y=t^2 can be plotted by using this equation x=sqrt(y)*(y-4). File attached. Example 2: Parmetric curve x=t^2 * sin(t), y=t^2 * cos(t) - "t" can't be expressed easily in terms of "x" and "y".(or is it correct to write t=asin(x) * (asin(x))^2 ?) Best,Sergey

I have been trying to create a simple while loop and just can't figure out the error Mathcad keeps prompting. Can someone suggest what the issue is here? 

I am getting error no solution found for solve block I tried to change the value for TOL and CTOL but with no luck

I used to have this problem when I had regular sheet. However, now, I'm using API and input everything using API, but my output isn't refreshing. I have to open, refresh and open again by hand. Anyone faced this issue before?  

Hi   I would like to subtract the values in the column by subtracting 2 from 1, 3 from 2, etc. and have results in a new column. Basacly i would like to have differences betweene two lenghts.

No matter what the value is it always passes to ok 

Hi, I'm trying to figure out the math for something that I did in CAD. Eventually, I have to code it in Fortran. However, I thought I should try in Mathcad first. I found some websites and tried to use the information they provided. For their inputs, I get their answers. However, when I try to use the real inputs from the CAD model it's way off and doesn't seem to make any sense. I'm not sure what I'm doing wrong. This isn't a Mathcad issue, just me trying to figure out the math. From what I can tell this is the point normal form of intersecting planes. I actually know what the surface normals are. But the values I'm getting from the math don't match at all. Ultimately, I need to figure out the angle between the intersecting line and the local xy plane (rather than the global xy plane). I tried to provide some pictures. I have triple checked my inputs and don't see any issues there. I suspect my math is not right, but I have no idea why. Anthony 

I need to know how to write the results to an excel file in a specific sheet and in a particular cell:no specific examples here https://support.ptc.com/help/mathcad/r7.0/en/index.html#page/PTC_Mathcad_Help%2Fexample_reading_and_writing_data_files.html Can someone please share an example as how to write into excel sheet for a particular cell   

Hello everyone,I would like to retrieve certain rows of a matrix based on an initial vector:Lets say I have the vector Lp and and I want to search the rows in the matrix M (based on the first column) in order to achieve the matrix Final.Note that the vector Lp can have more numbers as for the Matrix M (this is just an example).Is there a simple way to do this? Thanks in advance for your help. Miguel,

Hi, guys I am trying to solve this equation and get the value of coefficients (alpha1,2,3) and it doesn't work. Is probably 'cause of derivation. You have and suggestions on how to solve this? I would like to use it in the future, so it should be parametric.

I am unable to use the writexcel function in prime. I am not getting what is missing in here

Is it possible to change a Prime7.0 license to a new employee?   We are not seeing where that can be done.  Tried requesting a new license file, but webpage indicated, " invalid parameter values have been passed in.  The application cannot continue".  Not sure if we can't get this to work because:1) Since the employee left, Prime is now up to version 8.0, which is what we downloaded on new employee's computer.  Prime7 purchased product ID perhaps doesn't work with Prime8?2) Can't request new license files if the licensing is tied a particular person's name. We were able to dig up the 'host ID' on the new employee's computer - so we have correct Host ID, and Product ID, but can't get a new license file. Find it interesting that the only way to contact PTC for support help is to use login information, but we don't have login information as that employee is gone.  I tried to use my login information, but I'm not the user with the problem. 

I am using Mathcad Prime Release 7.0 and Datecode7.0.0.0Mathcad Prime 7.0 can show results in scientific notation, but if exponent is zero, the exponent is skipped.Is it possible to display always the exponent as Mathcad 15 can?

HelloI use MathCad Prime 7.0, to a lot of symbolic solutions, but many times it comes out in a long solution that could be reduced, but simplify can not do it. What should I use to make it shorter/reduced. 

Hello everyone,I am trying to automatize a calculation process in Mathcad, but I am having some difficulties doing it.Lets say I have a matrix with “n x m” number of rows and columns.In this example we can have the following matrix (5 x 6 – but it can be different, ex: 10 x 15, 9 x 10 etc...):Note that Ni is each row of the matrix.There is a variable “var” that can be equal to 1, 2, 3 or 4.And finally we have vector “V” (that has always 1 single column, but number of rows depends on the variable “var” however this vector is an input, the values below are just an example):I want to obtain the following matrix “M” depending on the variable “var”:- If var = 1 (“V” vector will have just 1 row – F1 = 10)- If var = 2 (“V” vector will have 2 rows – F1 = 10 / F2 = 1)- If var = 3 (“V” vector will have 3 rows – F1 = 10 / F2 = 1 / F3 = 4) - Finally if var = 4 (“V” vector will have 4 rows – F1 = 10 / F2 = 1 / F3= 4 / F = 7)Any suggestions? Thank you so much for your help, Miguel

MathCAD Prime 8.0 error

I am a new user of Mathcad Prime 8 and have created a collapsible area for constants/units etc. However I realise that while I expand the area, the content below the area is shifted downward, when I collapse it, it remains permanently shifted, creating an empty space the same size as the height of the collapsed area. So I have to manually remove the empty space. I am missing something or is this a bug? I do remember Mathcad 15 didn't have this issue?

Hello,   I'm using Prime 7 and want to convert some Mathcad 15 documents but for some reason the converter button is greyed out and not clickable.    Any tips how to get it working? 

Hello everyone,I am quite new at programming in Mathcad.I am trying to create a matrix using different vectors that are obtained based on a certain condition: I made an example with vectors N and M. The idea is to reach at the end the matrix "Final". Is there a way to use a for loop function to define the final matrix taking into account that the number of rows in the vectors N and M can change (but still equal)? Thank you,

Hi All,I would like to obtain a value of a variable from my worksheet. Let say my worksheet has x:=1 and y:=x+1=2. What function can I use to get the y value? I was trying with Worksheet.OutputGetRealValue(&As)("y") but I got an error instead. The following is my code: Sub test01() Dim WS As Ptc_MathcadPrime_Automation.Worksheet Dim App As Ptc_MathcadPrime_Automation.Application Set App = New Ptc_MathcadPrime_Automation.Application FileName = Application.GetOpenFilename(MultiSelect:=False) Dim conNum As Integer i = 22 conNum = Cells(i, 7) Do While Cells(i, 1).Value <> "" '' inputs Set WS = App.Open(FileName) Call WS.SetRealValue("#", Cells(i, 7), "") Call WS.SetStringValue("M1", Cells(i, 2)) 'Call WS.SetStringValue("M2", Cells(i, 4)) Call WS.SetStringValue("M3", Cells(i, 3)) Call WS.SetStringValue("M4", Cells(i, 1)) Call WS.SetRealValue("D2", 3, "") Call WS.SetRealValue("D3", 3, "") Call WS.SetRealValue("D4", 3, "") Call WS.SetRealValue("D1

I have done many FFTs of optical images and systems in Mathcad 15.  I convert them to Prime 8 and almost all of them will not display the 3d plots due to the error "3D plots must be less than 40,000 points".  Why?  They worked fine in 15. Also, you can no longer get a good smooth 2D image displayed as if you captured on a ccd camera.  Prime 8 doesn't allow me to generate theoretical images that I can compare to my experimental ones captured with the ccd.  Why was this capability lost?  Or is there a way to do it with 8?

Hi, i am doing some calculations on a project and am quite new to Mathcad. When using the solve block i keep on getting an error and i dont know how to solve this one. Any idea where i might be wrong? 

1) I've been working with Mathcad 6 Plus for many years. And it doesn't seem to me that the conversion gives the same result in terms of format. Do you have a comparison table or something similar to facilitate exact file conversion ? (With Prime8 ) 2) Can a spreadsheet be saved in a format locked to the user except for input variables without the user needing to own the Mathcad Prime program?  Thank you for the time being.   Translated with DeepL by Emily on Apr. 25th, 2022.   ---------------------------------------------------------------------------------   Subject: Formattazione   1) Ho lavorato per molti anni con Mathcad 6 Plus; e non mi pare che la conversione dia lo stesso risultato in termini di formato. Avete una tabella di confronto o qualcosa di simile per facilitare la conversione esatta dei file ?
