Mathcad

As per the original post.    Hi! Can you please help with my corrupted MATHCAD 15 file?

Good evening, I am trying to program searches in tables or matrix, if someone can help me. Thank you...   Translated by the Community Moderation using Google Translate.    Buenas noches, estoy tratando de programar búsquedas en cuadros o matriz, si alguien puede darme una ayuda. Gracias...  

HiI would like to have equal scales in x and y -axis of a 2D Chart component.In old Mathcad 15, there was a built in  "Equal scale" option.Is there something similar in Prime 9? I may have (hopefully have) missed some obvious thing...Thanks. Old discussion about this topic:Solved: Equal scales on Plot - PTC Community 

How i can fix the above problem. iam trying to prove if elements  delta matrix ( 10x1) are less than B =matric elements 

Is it my or Mathcad Prime 6 error?  

I am interested in Mathcad for the sole purpose of drawing contours based on spot elevations that are scattered (x, y, z), i.e. not in a unique grid. I'm testing Mathcad Prime 9 for this.I saw online that previous edition of Mathcad could do this, but I am unable to find the functionality in Mathcad Prime. Could you guide me to the speicifc process that I can use to achieve this. In summary, I have data points scattered in 3d space, with each data point having x, y, z coordinates. I want Mathcad to draw contours in 2D (axes representing x and y, with contours drawn between z values). An example of a process is described here, but I cannot find this functionality in Mathcad Prime (see Slide 53 and later):  https://www.foundationperformance.org/pastpresentations/ClarkPresSlides13August14.pdf The xyz data I am trying to get contours for is currently in an excel file, attached. Looking forward to receiving your feedback!

Good evening, everyone.  I was working on a model in Mathcad today. Unfortunately, I keep getting an error message every time. To prevent errors, I have removed all units. I have double-checked the function, but I can't seem to find the error. The error message I'm getting is "This value must be a function." I would say that this might be in the theta1(t), z2(t), and theta2(t). I have already reviewed the steps below:Check the ODEs: Make sure that the ODEs you are trying to solve are properly defined as functions of the independent variable (usually time) and dependent variables. For example, if you have an ODE like dy/dt = f(t, y), make sure that f(t, y) is a valid function.Correct Function Format: Ensure that the functions used in your ODEs are defined correctly. Mathcad Prime requires well-defined functions with proper syntax. Double-check your function definitions, including parameter lists and mathematical expressions.Function Inputs: Confirm that you are passing the cor

I am pretty new to this segment and it would be much appreciated if someone can share some demo parts in Creo Parametric which can be droved by mathcad prime 8 along withn how to do it.

I have attached three files.  FFT1, FFT4, and FFT5.  I'm trying to learn how to do a fast fourier transform.  I begin with a 1 microsecond sampling rate, which provide a max. nyquist frequency of 500 kHz.  I multiply the number of points in FFT4 by a factor of 10, so the sampling rate becomes 0.1 microsecond, which provides a max Nyquist frequency of 5 MegaHz.  Then I again multiply the sampling frequency by 10 and produce a sampling rate of 0.01 microseconds and a Nyquist frequency of 50.  Can anyone take a look and confirm this theory?  How do I reproduce a segment of the output FFT?  I want to reproduce the segment above n=50 MHz in the final spreadsheet.  How do I reproduce the segment beginning with n=0 and ending with n=50 in the FFT5 spreadsheet.I want to reproduce the original waveform as well..Any assistance understanding this software would be welcome.I also need to know what dft is doing relative to FFT.  I know it

HiI am trying to find 4 unknows from an equation. But its giving me "0" as a solution. I have eight know variables in the equation, while I want to find the rest of 4 unknowns. Your help would be highly appreciated. I have attached the sheet of Mathcad 9. Best,Waqas  

Having a problem here, every time i try to perform a simple matrices multiply function, it shows as invalid array index , but surprisingly the same thing has worked in other systems.Please help. Have tried defining everything separately but the problem persists.     

Hi, Have tried all I know (which is little) for a couple of days now.  Could someone explain all the steps including how to set up the Visual C++ Community IDE steps to get the provided multiply() custom function to work in Prime 9? Cheers Terry    

Hi, I'm having trouble finding a symbolic solution I can use in an excel sheet for later use.I am aware that it's mabye impossible to find a symbolic solution. But I was hoping it was, And that you guys could help me? All the values is >0 Erik

I am using MathCAD for the first time today, and have a problem that requires your assistance.  I have to create a waveshape, and I do so, but the points are separated by 1 unit, not the 1 microsecond units that  are the reality.  For this reason, I have no idea what the output of the FFT X axis is.  I've given it no frequency reference, so is it using 1 Hz as the basis for the difference between each point I've entered (not the truth).  I'd like to know how to get this software to accept 1 microsecond as the difference between each point that I enter.  I also need to know how to interpret the output of the FFT.  The spreadsheet is here: Re: How do I change the graph in the attached file... - PTC Community There are various example mathCAD sheets attached.  I've tried various things, but can't get them to work. Thanks. 

How do I change the graph in the attached file so that points are all 1 microsecond apart? Using MathCAD 9.0, PTC.  The latest.

Hi have successfully compiled the multiply(a,M) example custom function but have a few questions. Q1> Do you compile for x86 or x64 seeing as PTC Prime is 64 bit? Q2> Where do you find the custom functions as neither the Prime menu or the search for all functions has a section for custom functions?  Mathcad 15 search had a specific spot. Cheers Terry    

I have an old Mathcad file (14) I convert it to Prime 9 but the code does not work. Please help  

Hello, PTC community,   I defined a function in Mathcad prime 9 for plotting the displacement response (Y-axis) versus time (X-axis). This plot is for a single time period T.  I want to get the maximum displacement (Y-value) from the graph for each time period T.   For example, I want the maximum displacement values from the plot for Time period T if T= 0.02, 0.2, 4. eg T= 0.2        max. displacement: xx T:0.4          max. displacment xxx and so on.   I attached the mathcad file and it imports a text file containing earthquake data which is also attached for your reference.    I would really appreciate your help.   Thanks, Abdur    

I am attempting to evaluate a ground motion data set using Newmark's method. The programing routine augments displacement, velocity, and acceleration. I then need to plot the displacements vs. the time period as it varies from 0.02 to 4  in steps of 0.02. When I define T I get the following error :  I don't think a local definition with in the routine will yield accurate results. The routine needs to run as a function of T.     

How do you go about getting to the next "step" in a formula? Like in a division situation where you have filled out the numerator, and you want to get to the denominator without using the arrow keys. Or in an if, then statement, getting to the next gray box? Or to the end of parenthesis in a formula? In short, how do you avoid using arrow keys to get to the end of the formula you are writing? thank you

Why am I getting an error when I move g below k? Shouldn't global variables work where ever they are used?   -->   so, this seems to work ... ... So is it not possible to have global variables inside global variables? if so, why did the first set of calcs work?  Thank you in advance

Is there still no way to have custom keyboard shortcuts? I found posts dating back to 2015 saying there is no way to do that in Mathcad. That was the latest post I could find. Any chance that has changed since? Ctrl + Shift + ~ is super awkward to do for global variables. thank you

how would you do the following in Mathcad:  if  (x = 1  or x = 2)     return "yes"else     return "no"  thank you.

The plot is changing enormously when ode solve is used. Any suggestions? 

I have enormous number of .xmcd files needed to be converted to .mcdx. Inside most of them there are links to each other. Considering nested structure of my files and the fact that you can not choose the whole folder for nested convertion in built-in MathCAD Prime Converter I need to automate at least filling Converter with list of files. Would be even better - to make the whole process fully automatic. Have someone done this before? Is there any API for the Converter? Nothing like that was found by me in the PTC support database 😞There is some kind of workaround - to generate multiple paths to files relative to the root folder and join them with " "`s but resulting string is far too long to be accepted by the FilePickupDialog of the Converter. Too many files needed to be converted.
