How to add a digital BPF (FIR/IIR) to the sampled data?

HiWhile working in mathcad prime 5.0 i had an error and file was closed. Fortunetly the backup version has been made automaticly but it doesn't open and appeares an information that the file type is not supported.Can I restore somehow my progress in my file?

See the attached file. When I try invlaplace in Mathcad 15 with a simple s-function, it works, but with a slightly more complex function, it doesn't give a useful result: I am a very infrequent user of Mathcad, so please bear with me if I ask stupid questions. I do not understand the repeated 'invlaplace' and the 's,t' part of the result. I expected a function of t that I could plot after including the numerical value of omega. Setting t=35 and [omega] = 2*pi*t doesn't help. I tried putting ', omega' after the first 'invlaplace',  but it produces no more useful result.  

Hi,  I need to export the data from excel component & to print in single matrix (3X3), can i please know the format to do that.  

Hi, I have 30-days Mathcad Express Prime 2.0 . I have to open my .xmcd files but i could not because there is not active the Converter XMCD, MCD. Please help me.. Thanks...

Good Morning Community,   Would anybody be kind to look into the Mathcad sheet. My goal is to read Steel section properties in the attach W.prn file into Mathcad, but I was getting an error messages. Please help.   Best Regards   Moses

I have been a long time user of MathCAD. v15 is great for calculationa but poor on reports. Prime appears to have been an improvement on the report writing. For this reason I have started to learn how the program works. One of options I have been using is eBooks. I is great at organizing information and reports in MathCAD. One functions that is particulaly helpful is hyper linking. Does Prime have this functions? Thanks for the help in advance. David Tg

Hi is it possible to create phase diagrams like this one I have attached and how?

Using Visual Studio 2010 to build Custom Functions in Mathcad Prime 3.0.

Hello,   I am trying to evaluate the derivative of a function symbolically. Would anybody, please, help me with this issue?   Best regards, Sergey  

I cannot figure out how to change the font type and size on an axis in any plot. I cannot see the values on an axis without zooming in. Copying a plot to paste into another document leaves me with a graph that is nearly unuseable. U can change the axis label fonts easily enough but the actual values on the axis is impossible. I certainly must be overlooking where the command(s) are to do this.

Hey guys,   I was working on two files where mathcad suddenly hanged and shut down, now the files can open but last few edits are missing. How do I recover the missing edits? Can someone help? I also noticed two new files on the desktop (where original Mathcad files are) .tmp, now I attached only one file but not sure which .tmp belongs to it.   The files are attached

Hi guys as you see I am using this matrix and want to find eigenvalues and vector but dont understand the difference between two numeric and symbolic solutions, why are they different?   Thanks

Werner_E recently instructed me on how to utilize the root function but now that I try and implement it I think that Prime is manipulating the storage of that functions return values in new variables which leads to inexplicable problems down the line.    Here on page 2, I use root and store the values in alpha and beta however Prime sets their label to "keyword" and presumably that is interfering with the integration on page 3. I try changing the label with the drop down menu but PTC is not having it and the label reverts back to their pre-set. What gives?

hallo, würde gerne wissen wozu diese Option ist? Auswertung aktivieren/deaktivieren....und wann man das benutzt ?   danke !

Hi someone who can help solve this can't make it work....

I found the classification made in this site regarding mathematical software very interesting. What do you think?: https://en.m.wikipedia.org/wiki/List_of_computer_algebra_systems?fbclid=IwAR0mqtZPNUMfAmh4oFQne2gHasSVaEmNJSsCGDfxiC33Sr56vwQXNowgEHM

hey guys, I am trying to change a value T in a program, and its not changing, why is this happening? thanks! Photo is attached

Hello PTC community,   I searched all over the internet, but i could not find a solution for my problem, with my limited knowledge of mathcad usage (civil engineering student). I have attached a picture of my table that i have to interpolate the values. it kills me that I can not solve it. i have looked at all topics about 2d interpolation, but i couldn't not understand to reproduce.   I will be very grateful for any help!

Hallo,   ich versuche die Funktion F(x)=x2 darzustellen, was habe ich falsch gemacht ?! Danke im Voraus

Hi, I want to obtain eigenvalues symbolic equation for the matrix. Any help would be greatly appreciated. Attached file. Regards

I was trying to solve for a function and i believe it gave an incorrect solution as i verified. Can someone please assist? Thanks

Here we have tried to find a symbolic solution for the problem of two cones. But we can cut out three cones from a round billet! We can show with the help of graphics and numerical mathematics that the third cone is superfluous - the maximum total volume can be only for two cones.Can we show this using symbolic MATHEMATICS? See please pics and Mathcad Prime 5.0 sheet. Fig.1Fig.2Fig.3Fig.4Fig.5Fig.6Fig.7Fig.8Fig.9Fig.10          

Im a newbie in mathcad, im using mathcad 15. My problem is that somehow polyroots isnt working properly for me. I attached an example, which explains my problem. My original task is to create a program, which solves a function, similar to the one u can find in the example file. One of the coeffecients (the constant) is the function of time in my task. Then i have to pick out the appropriate real root and illustrate it as the function of time. Unfortunately polyroots is the only suitable way to execute the task according to my short term mathcad knowledge. Thanks for the help!

To all expert,A simple question on the use of the ‘simplify’ option in mcad 15. I was looking at trying to simplify some simple equation and after some simple manip I ended up with:            f*B / SQRT(f^3*A*C) which can be then simplified to            (1/sqrt(f)) * (B/sqrt(A*C))                    I was interested in “extracting (B/sqrt(A*C))   Question: Why is mcad 15 not able to further simplify the term f/sqrt(f^3) ?   Thanks Regards
