How do I get Prime 3.1 to make use of WaterSteamPro? I see from various postings that it does now work, but I can't get it to work; I get "Variable not defined" whenever I try to use a WSP function.I have copied wspmcad.dll from the Mathcad 15 userefi folder into the PTC\Mathcad Prime 3.1\Custom Functions folder. Is that correct? Is there enything else or different that I should be doing? It worked for CoolProps, but seemingly not for WaterSteamPro.I tried Prime at version 1, but gave up in disgust. This is my first time to use Prime since then. I am probably making some fundamental mistake. But I see a couple of postings by Valery Ochkov showing WaterSteamPro working in Prime 3.0 (eg messages #222892), so I know it should be possible.

    Hello, Everyone.   Thanks in advance for your time and help.        Regards.

Hello All,Last instalment on Fourier.Next on Prime/Mathcad 'signal processing function' pack.Just here there some topics in the chapter.Maybe later on Laplace and Z-transforms, after my immediate items on the things to do list..I needed to practice it for smart grid textbook I plan to start working on soon.Karl.

I need to solve the equations for X,Y and Z.  My current issue is I need a single equiation for each to solve the system.  What is happening is I end up with a  +/- solution due to the radical in the denominator.  So how do I get MathCAD to use just the positive value and solve for all three variables?

hi everyone I need to make one homework with "Successive Gauss elimination method". Text is:Deploy successive Gauss elimination method using palette Programming for solving the system of equations:

I am uploading an example where i created an excel table with component and added 3 vectors as input. If i arrange the number it works fine but when i press the mouse somewhere else to go out of the excel format it mixes again the numbers

Hi Everyone I would like to know how to include a database that allows me Mathcad Prime extract specific values to my calculationsEXAMPLEAS THESE COULD TURN TABLES OF EXCEL AS FOLLOWS?I'm starting to use this tool, I would greatly appreciate your help

alfa = 21.0375please clarify, how two solve the first 2 calcualtion

Hello,I wish my email finds everyone happy and sound. I need to reverse the scale in a graph that I have attached . The graph is z vs u(z). I need to start the scale values in the graph form lowest at the top and highest at the bottom. I will appreciate if you can help me with this.ThanksFaisal

Dear,Please find attached my qurey. Please explain how to use solve function in the attached equation

Hello community,I have a problem with using mathcad 15. When I start the program and open a new sheet, all i can see is a grey window (see screenshot attached). Also when i open old mathcad sheets, no caculations are visisble. When I scroll, some numbers blink up-but just for a very short time. So it looks like mathcad is acutally working but a grey mask is upon my numbers/calculations. I reinstalled the program and changed settings in order to solve the problem. Unfortunately nothing was successfull so far. Does anybody know the problem or hast some good andvice?best regardsBenjamin

Hello fellow MCers,I have a problem with a data set filter. My aim is to have a function that creates out of a given set of data points another set that contains 2 to the power of k elements being randomly selected; with k an integer.So I created these functions in MC15. The annoying fact is that it works fine when I have a data set whose number of elements is close to 2k; e.g. 525.However, it fails to converge to a solution if the number of elements in the initial set is close to the next 2k.E.g. data set containing 555 elements. It puts out a 512 element vector - fine.Change number of data elements to say, 999, it has troubles finding a solution. Whereas the next 2k element size of 1033 yields 1024.My suspicion is that it probably has to to do with the way I'm generating a set of random integers (for the trim function) by invoking the runif function and truncating the real numbers to an integer.Thanks in advanceRaiko

It's time for my semi-regular update, rationalization and general cogitation on the whichness and the whereforeness of multi-dimensional arrays (MDAs) in Mathcad.   This time, I'm going to start off with a revamp of my Nested Array support functions.   To kick off the process, I'd like to present the shape function.  shape is intended to specify the structure of a nested array with the intent of being able to both generate and populate an array given this specification.shape(A😞 returns the number of elements in each dimension of A. If A is not an array (eg, a scalar, string or function), then shape returns 0.  If A is a vector or (non-nested) array, then shape returns a 2-vector giving the number of rows and number of columns in A. If A is nested and all the elements of A are arrays of the same shape, then shape returns the shape of (one of) the elements. If A is nested and the elements of A have different shapes, then shape returns an array showing the s

Hello,I am currently working on a project in Mathcad. With some help of Google I was able to make everything work.Except one thing... I would like to output multiple variables from a for loop. Or I would just like to access them AFTER the for loop.Something that I've been trying is this:The output of the for-loop is X. Now when I show X, it shows a matrix with 3 elements. But I am not able to retrieve the contents of the matrix.If I try to retrieve the first column it returns ({789,38}), but I would like to get the matrix I inserted back.Thanks in advance!

Prime: How to create an " ellipsis" of a long formula or break it up so it fits in one page? I have very long formula and do not fit in one page. I will like to break it in 2 or more parts so it can be shown on paper (1 page fits all). How is this done in Prime? see eg.

My next chapter is on Fourier Fast Transforms then followed by Prime Signal Processing Pack. I had come across a number of signals and systems books, mostly at the undergraduate level and were published by USA authors. One book at UG level I had purchased close just over 8 years ago for me came to be the most detailed, thorough, and lucid. I had read more in it than I could remember, I needed it to refer to some material and I came to remember how much I had already read. I like to share the title with you. If you are going to be serious signal and systems person this should be on your shelf.The author has another book on signal processing, but this is on UG signals and systems. Published in UK and elsewhere.Linear Systems And Signals 2nd Ed. by B.P. Lathi. Publisher Oxford. I recommend signals and systems be a 2 semester course. There is too much material to cover in 1 semester, and running thru it in 1 semester will pose difficulties in other related courses.  Too much material

Hello All,I have two worksheets:1.  Fourier Transforms 2. Sampling with Fourier (Next Post).They are not as clean as the Fourier Series more on learning outcome.In sampling a signal was taken thru several steps to get the final sampled signal with a filter applied.If there are any major errors which there might be let me know.Not using the signal pack functions, just the mathematics of Fourier to apply to the signal.Cheers and Thanks.Karl S Bogha.

Hi,When I print to pdf in Mathcad 15 I always get random horizontal lines that show up in the pdf file. When I print to paper printer it's OK and when I print preview they are not there. The lines only show up in the pdf created document. They are usually over half to 3/4 of the page.I've tried multiple different pdf programs but the bug is common across all of them.How do you fix this, has someone found a free pdf writer that doesn't have this issue?Please excuse me if this question has already been answered, I couldn't find the question / solution on here.Thanks,Dave

If i have a vector A=(0.45, 1.78, 0.82, 0.95, 1.99,  1.12, 0.77), how to create a vector B that contains only B=(0.45, 0.82,  0.95, 0.77); only values that are lower than 1. The other values may be 0 for example.

Hey guys,i have a very special problem with the equations i postet here. I dont get rid with a right formulation with the on error function. My problem: during a very long calculation i need to make this Iteration calculation. Sometimes it is possible that the Iteration here is not finding a value for Dp. When it is the case, i want to use DShr insteat of Dp.When using DShr insteat of Dp, %D1 is 0 and i can quickly see, when the Iteration is not finding a value. But my problem is that im not getting rid how to correctly define the on error function as vectorising. Because it could be possible, that the first row is OK and only the second ROW of the input vectors lead to a problem in the Iteration. That on error function needs to vectorise Plzzzzzz help me,Thx, Stefan
