I met strange situation with match function.That`s the problem?With unitless V all is OK

Hello,I was wondering if you could help me with symbolic Fourier transformation. In the attached file, I want to see the symbolic expression of i=fourier(I).I appreciate your suggestions in advance.SincerelyPayman

hello every onei have a little problem when defining a range variable, and its  that the variable doesnt display and i dont know why. if someone could see it and tell what's the problem it would be great.

I have a work sheet I use and it runs properly on a Windows 7 machine in Mathcad 010 but it fails to work in Mathcad 045 working on a Windows Surface book OS 10.the command isAny ideas?Is this a problem in OS or changes to MathCAD from 010 to 045?A

Hey guys. I have units problems when i use protencies and square roots. Can someone explain how i can solve this problem? for instance in the attached file i should have kN instead i get no units.

Can someone (or several) offer some comments about advantages of one vs. the other? I realize that could be a long answer and I am just looking for some general guidance. I have been a longtime MathCad user (though not necessarily a particularly adept one). Recently I decided to learn Matlab and started doing this by rewriting some Matlab programs in MathCad (although the reverse might seem more sensible). Although MathCad has obvious advantages for combining text and calculations in a more or less free form way, my impression is that MatLab offers many programming advantages. For example, fzero seems to work more robustly than root, MathCad seems to have no function equivalent to fminsearch or fminbnd, it treats NaN differently (MathCad returns 0).Attached is a MathCad worksheet and the equivalent (?) Matlab files.

In addition to last mail from Thursday there is attached a file with two versions of the program block mentioned.The program block Largefile.mcdx is the long version, which Prime 3.1 refuces to calculate (to big).The second program block Largefile_red.mcdx has 18 comment lines less than Largefile.mcdx and workes propperly.Input data to perform the calculation are included.Mathcad 14 can handle the larger program without problems.Günther Polz

I am using a program of 120 lines length, that can be handled in Mathcad 14 without problems.Prime 3.1 however indicates "This expression can not be calculated because ist is to large".Is there a general limitation in Prime 3.1 or is the problem created due to the transfer form MC14 ?Günther Polz 

I've recently reloaded MathCad 14 onto my re-imaged Windows 7 computer on which it used to operate but the program will not start up. The icon on the task bar 'glows' and then dissappears without any request to find the licence. Has anyone come across this before and knows the answer?Thanks in advanceRichard

Hello AllRecently I have been working on my mathcad file which  include formulas and some pictures and it worked fine for a while. I was able to close it every single day  and open the file next day. But today I cannot open the file. The application I have on my system is PTC mathcad prime 3 and I havnot updated or change it since I installed it on my machine. I'm able to open other mathcad files but not this file. The log file says:Exception data:File being opened: C:\.....\Desktop\MyCalculation.mcdxFileFormatException when processing fileSystem.IO.FileFormatException: File contains corrupted data.   at MS.Internal.IO.Zip.ZipIOEndOfCentralDirectoryBlock.FindPosition(Stream archiveStream)   at MS.Internal.IO.Zip.ZipIOBlockManager.LoadEndOfCentralDirectoryBlock()   at MS.Internal.IO.Zip.ZipArchive.OpenOnStream(Stream stream, FileMode mode, FileAccess access, Boolean streaming)   at System.IO.Packaging.ZipPackage..ctor(Stream s, FileMode

I'm solving the natural frequency of a structure. Pleas help. See attached file. How to do this in Mathcad Prime 3.0?

Hi all,please see attached.I am attempting to derive what I thought would be a simple enough equation to describe the maxima and/or minima of a "filter" function magnitude response.  The example is a simplified version of my original problem and although in this case the answer is very obvious (w = 1), my original problem did not have so obvious an answer,  And also, although I can easily plot the response, I would like to establish the design equations to allow me to work backwards from a requirement to a solution in equation form.In the worksheet, the symbolic solution seems to fail.  I specify the function H(s) and then substitute s = 1i.w to obtain continuous frequency response.  I suspect the problem is complicated by the use of the |magnitude| function which might make symbolic solution difficult - that's my guess at why this doesn't seem to work.  If there is a better way then please let me know!  I have been staring at this on and off for a few day

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
