Mathcad

I have a list of x, y, z coordinates that I'm trying to plot within a contour plot, but the resulting plots aren't returning reasonable scales... Was wondering if anyone has ever done anything like this and if they could share the format they used to plot said data? Thanks in advance

I believe the title says it.At first I though it might be related to having a Plot nearby or the text box overlapping.Then I thought it was related to multiple colors of text.I haven't quite narrowed it down, just wanted to bring it up for developers...(lol--do they read this?)I am using Express.  Maybe my file is just getting too big (although it is still smaller than 1 MB).

Three files are attached:DATE.csvDATA.csvDATE.xmcd When reading the two csv files into the Mathcad file, the first element of the DATA file is corrupted and looks likeHowever, the DATE.csv file reads in correctly as: What is causing the corrupted first element when reading in the DATA.csv file. Thanks for any help provided.Reg Curry   

I am wondering , what is a precise tolerance and what is a loose tolerance. I would imagine that from 10^-1 to 10^-9, loosest tolerance would be 10^-1 and tightest would be 10^-9. Please correct me if I am wrong. I also had question if I could overwrite tolerance even further? I want to loosen my tolerance even further since my solve block is not converging for 10^-1 (Assuming it being the loosest tolerance of all). Thank you in advance.

Hello, I'm not that experience with Mathcad, I do with excel, there the index match function is quite handy, something similar I would like to use in MathI would like a lookup function in a matrix, to return as output from the matrix, not the value, but the name: I'm not sure if it's even possible, have searched throughout the internet without results.. Thanks for helping!

I checked this section for a similar question and could not locate one. It's simple one I'm guessing but I just cant figure it out. Two equations: 3x^2 + 4x -7 and 5x^2-7x+3 (or whatever one variable equation). How can I add them in mathcad so I get the answer 8x^2 -3x-4 ? Thanks. Mr Noob....

Hello everyone!Why does the symbolic processor give me different results in calculating the sum of the infinite series shown in the photo? Does Prime produce the same results?

Hi guys,   I have a question.. I modelled a 4th oder ODE in MathCad which works smoothly.. But when I tried to upgrade the script into (a system of ODE’s) 3 or 4 ODE’s, I couldn’t get it well working.   Note that I checked the boundary/matching conditions and they are correct. So something else could be wrong.   I’ve included the file in the mail.     Would you like to help me here?   Thanks in advance!  

Hello all, I believe I am suffering from a similar problem to a previous post; Solved: Mathcad Prime worksheet Running Slow Compared to M... - PTC Community I have a legacy calculation converted from Mathcad 15 that is mathematically very simple but approximately 170 pages long and as you will see from the attached is butchering my cpu.  The aforementioned Prime calculation is consequently running painfully laggy and occasionally crashing.   Does anyone have any recommendations on a sensible procedure for processing such conversions that goes beyond the standard PTC Mathcad Migration guide? For example, is it advantageous to break the calculation up into areas and disable them etc... @VladimirN , @terryhendicott 

Making some calculations with MathCAD I got an error such as: Unknown error: A call target threw an exception.Is there some stack trace which I could investigate to comprehend the situation? Thanks in advance. 

I converted a part of file from my Mathcad 15 worksheet and getting the error due to this i am unable to proceed with calculations Can it be converted somehow?

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.
