Hello,     Mathcad Prime 8 file attached.    

Several cities have installed arrays of microphones and use the time delay of the sound of a gunshot to triangulate the location where the shot was fired.  After several months of stumbling around I managed to get Prime Express to do this calculation.  (In my previous life a solve block would have made the job simpler.)   So let me crow a bit!  Prime 4 Express attached.

Hello.Our company had a PC that acted as a license host. Recently this PC has crashed.  We raised a virtual server in order to transfer the existing licenses to it, but the error occurs: "Upgradable products not available or already used on provided Product Code". And it is not possible to untie licenses through your personal account, because "Complience Hold".  Tell me, please, are there any other options to restore licenses?We have MathCad Prime 3.1

Hi,I'm trying to understand how the IFFT works.The most difficult thing to be understood by me is the reason why, having 2049 complex samples (p0) I get as a result (4096) real numbers.The complex samples are not generated by me, are the result of an algorithm written by others.So I try to understand if there is something special in those samples.I tried to compare the result with what I get with Wolfram Mathematica (sorry about that):InverseFourier[p0, FourierParameters -> {1, -1}];and I get (2049) complex numbers. To get something similar in shape I need to take the real part of those numbers.Beside that the result of the IFFT is 2048 (magic number!) larger than the result of the InverseFourier.Can anyone explain to me the reason of those "mysteries"?Thanks 

Hi, I would like your help to convert MathCAD 15 file to 7 Prime (see attached). The conversion dialog shows conversion failure. Thanks, -Peter    

Hi The copy paste function is not working when I am trying to paste in word document, as I am using Student license any suggestion to copy the material.        

Hi experts,I am trying to plot this equation.Could you please tell me how should I modify the equation, thanks.  

Hello, I have been trying to solve this DAE system using MathCad Express Prime 9.0, but I have tried several things and I won't run. Can someone please take it a look and let me know why it does not work? Thank you very much.   

Everything seems correct, but my graph doesn't come up...any ideas?!? Thanks.I don't see how I can insert my document here...or I would                

 

This month’s challenge is electrical engineering related, but with multiple voltage potential sources in addition to resistors. See the image below. Scenario 1. We have a circuit with a motor (modeled as a 100 Ohm resistor), a 6V voltage source, and a 100 Ohm resistor. Calculate the current in the motor and the resistor. Scenario 2. We add another loop, with an additional 8V voltage source and a 120 Ohm resistor. Calculate the current in the motor and the two resistors. Scenario 3. We add another loop, with an additional 10V voltage source and a 140 Ohm resistor. Calculate the current in the motor and the three resistors. Scenario 4. We add another loop, with an additional 12V voltage source and a 160 Ohm resistor. Calculate the current in the motor and the four resistors. Note that these situations cannot be reduced to a combination of series or parallel resistors. There is a principle called Superposition you can apply instead. I’m looking forward to seeing what Mathcad techniques

I'm trying to figure out how to create a math variable name that includes both subscript and superscript characters like below:  The subscript is no problem, how do I get the superscript portion? Not just in a way that will let me display this text, but will allow me to use this exact variable later for calculations.  

I had the MathCad 15.1, and i use the code below to save the Sheets as à Pictures using the pdf creator.Now, I am using the PTC MathCad prime 8.0 and the code is not working.

Hi  I have a problem to show my results in a table where the column will be given "t" and the rows will be "Pwf". If there's anyone who can help me, please.  In the picture I use only t_0 in the formula and I would like to use all values immediately and present the result in the matrix 4x11, help me, please      

Hi! Please, help me before I lose my mind finally. I have this simple while loop which is working just fine most of the cases but not now. I understand that the problem is with indexes but I just cannot see the solution. Please find the example file attached. So what I'm trying to do is to compare the arrays xf and hs. Please see also the attached picture. I would want to get points compared and sorted like in the picture. From smallest to largest. English is not my native so I thought the picture would be more than thousand words. Feel free also to suggest more simple way to do this if you like. Bear in mind that the dimensions and number of "i" usually changes with different cases I have. But one thing doesn't change and it's the number of equally divided spaces = 8. Thanks a lot for your advice in advance! -Harri

Hi! I have a very bizarre error that I just can't solve. See the following:This gives me the "units are not compatible error" if I use t_uZkplus.max. If I put the solution for t_uZkplus.max manually in the lower line it works just fine:I really don't understand what is going on here. Does anybody have an idea?

 

I am trying to do a example from the MathCAD example "Generating Random Numbers"and it doesn't work properly. The norm function it doesn't show the proper plotting.Also the other examples from the tutorial, are hard to be plotted: scalar representation versus array.If you do a new version of software why there are no updates in the examples provided to reflect the version and changes in the software updates.Nevertheless in the example are some mistakes in the variable names that I correct them.It is something there, that I am doing wrong?   

Hello Everyone.From : refer to :https://community.ptc.com/t5/Mathcad/Gauss-Jordan-rref/m-p/273580#M106899 How to correct Gauss_Jordan.mcd for determinant ? Thanks in advance for your time and help.Best Regards.Loi.

Hello community, does anybody happen to know whether there is such a thing as a config file for Mathcad Prime? The issue is that I'm fed up telling Prime after each conversion of a Mathcad 15 file that the document format is A4 and not letter. In a config file I might be able to instruct Prime to check for that parameter. Thanks in advance    

Is there still no way to set the plot font size in mathcad Prime 9  

Hello,       I think that I reached the full capability of Mathcad Prime 8 regarding the symbolic calculation. Or I am wrong?   Can somebody run this sol2 determinant in Mathcad Prime 9 to see the result?   Mathcad Prime 8 file attached.    

I would like to Create Function by ODEs solving. I can do it if I have one ODE - see please the picture But if I have 3 ones - see please the attach Prime 6  

Is there any option to get the same behavior as listbox in prime? 

I have tried several speed tests, using return and not using return in a function.  It is hard to detect any difference.  Is there any reason to use return for a function that does not have any conditional breaks, that is, executes top to bottom and exits at the bottom? Regards, DS
