Hi All!On two PCs I installed mathcad 15 (on one OS Win 7, on the other OS Win 10) and on another mathcad 14 (OS win xp sp3). Among the one and the others I find differences in the fonts. For example in one's French MT script, while in the other there isn't. So it is obvious that importing programs from one to another there are changes. How do I avoid this?Thank you very muchF. M.
Hi everybody,I am trying to build a function that should give back two vectors (and that is not the problem), only those vectors have different units.The only way I can imagine is to adimensionalize the vectors, using UnitsOf (or SIUnitsOf) and the assemble them in the array of vectors that I want to get back.Somehow this it is cumbersome and error prone, since outside the function I will have to multiply back the variables by their units.Thanks a lotBest regardsClaudio
Hello!What's wrong with the last Fourier-Analysis of a sinus Function?Thank you for your Help.Volker
hi,I'm looking for a way to solve a two equations systems with x combinations of inputs values what should give the same number of solutions. Any help will be much appreciated
Is it a bug? The vector V must have an unit m!

Good Evening Mathcad Community,Would anybody please help me with the attached file. My goal is to do interpolation given a period T.a =0.5*sec, based on site_class and the header Sa(0.2*s) for Fa(site_class, Sa(Ta)) and same for Fv(site_clas,Sa(Ta)), I'm having problem as to how to program this in Mathcad. I will appreciate this if anyone can help.Regards,Boyetr
Hi all,please refer to attached files (Prime and Mathcad versions).I have a 3 functions:1) Ha(s,...) - a filter function (not really important what it is)2) M(s,...) - magnitude of Ha(s)3) D(s,...) - derivative of M(s)When I plot M(s) and D(s) with s replaced with iw, I would expect to see the derivative function have a value of 0 when the magnitude is at turning points but this is not the case. Can you spot my error?Thanks,D.
HelloWe are trying to integrate a function which contains a vector for wave frequency (omega) with respect to length (y). We need help programming the integral so that it gives a value of each value of omega. Currently it either gives us a single value, or says the solution does not converge.Any help would be greatly appreciated!Kind regards,James and Daniel

I just purchased Mathcad Prime 3.1. I only want to install Mathcad 15.0. I do not want Prime on my computer. I did download the file for Mathcad 15. Can this be done? Are there written instructions to do this? Instructions to do what I want are not with the delivered software or on the website (where I searched).
At the bottom of the attached sheet I am trying to solve for lengths YD and ZD that will work for all three equations simultaneously. It is telling me ZD is undefined. Is this because there is no solution or that I am doing something incorrectly with the solve block and the matrix guess values? Any help is appreciated. Thanks. The file is MathCAD 15.
I am using the find function to return solutions for a system of three equations. I understand that the solutions returned can be different based on guess values and tolernace of the solver. currently I cannot get the solver to return the correct solution. I am checking the solutions by using the outputs to recalculate one of the given equations.Is the find function not the correct way to solve for these variables? Should I be using arrays, or Max/Min of function. I am very new to Mathcad, and I am trying to use it to eventually input a matrix of ID, and Delta to return wall thickness (Ha) for various sizes.Thank You, and sorry for being a Noob.
Hello everyone.I'm trying to calculate the diagrams of bending moment and shear forces of a beam, I performed two analyzes, one starting from the left side and the second from the right side, but I could not get the same results. Hope someone can help me.Thanks in advance.

I would like to split up a single vector into a table. I would like to take e.g. each time 8 data points and put the next 8 at the right side thus constructing a table. Apparently I am overlooking something evident could someone help me out? Thanks in advance (MC15)
Hello Everyone.Is there a way to transform mutually form I and form II ? Thanks in advance for your time and help. Regards.
Hello,I am having trouble getting a solve block to solve a set of three equations. Error message is nondescript and I am not getting anywhere getting it to solve. Any help appreciated.
Dear all,I'm new user of mathcad prime.I'll try to solve a differential equation reported in the examples but I obtain this error message.How can I fix it?RegardsStefano
I just began working for this company and we have around 2500 .MCD Files from Mathcad Plus 6.0.Mathcad Plus 6.0 works okayish on Windows 7, however printing makes it freeze.So I thought I would give the newest Version of Mathcad a try and wanted to convert one of those files to the new format as that seems to be neccessary.However the converter complains that I need Mathcad 15 installed on the system.So, it seems we are stuck with Mathcad 6.0 as there are no update files for this version.Any ideas?
