Can somebody tell me what is wrong with this definition?See attached Prime8 sheet  

Can you give me a proposal for the fastest possible way for excluding all non-integer values from array? 

Every function, which is called with an argument of NaN should deliver NaN as a result !Some functions deliver odd values such as log, ln, or ln0. Very problematic are the functions min and max which deliver min(NaN)=0 and max(NaN)=0. This can lead to incorrect results, as it was the case in our calculations. This error occured with Prime 8.  

Hi guys, so I am having this problem with ploting graphics, I only need to do this simple Fourier Series and plot it, but it doesn't work. I will show the problems with some images and the program itself.   

Hello, how can I find position of known element in matrix if I know that element exists in matrix (column and row index). I tried with match function and I put small value for tolerance (as you can see in attached file test.mcdx) and I'm getting 2x1 for which I know that is not the right position. Also, it would be nice if you propose me the solution with separated index for column and for row.Thanks in advance!

I am using Mathcad Prime 5.0.0.0, Windows 11, for the first time as instructor in a civil engineering course having taken over from the previous instructor mid-semester.  (Ordinarily I use Matlab.)  My worksheet is supposed to solve the differential equation for liquid spilling out of a small hole in a tank modeled by the ODE dh/dt=-K*sqrt(h) in two ways: odesolve and rkfixed.  Here are the glitches I encountered: 1. Plotting functions h(t) (the exact closed-form solution) and q(t) (the output from odesolve) did not work for me.  I received an error message about complex or infinite values.  However, it is clear from its formula that h(t) cannot take on infinite or complex values.  In addition, Mathcad repeatedly changed the units of the t axis from s (which I typed) to 1/s * s, which is incorrect. 2. The exact solution to the problem exists and is well defined up to about t=85000,  After that point, the tank is empty and the ODE is undefine

I recently installed Mathcad Prime 9.  I had been using Prime 8 for a while. I have some files created with Mathcad 15 files (xmcd) that I need to convert to the new mcdx format but the conversion utility is taking a very long time to do the conversion.  It's been on "In Progress" for almost an hour on the first file.  I don't recall this being such a problem with earlier versions (Prime 7 and Prime 8).  Please help!   

Hello,For 2D plot we can see labels somewhat on the axis to see what axis is assigned to what variables for better understanding:     My question here for 3D plot: Is it possible to put labels on the axis like I shown below?    

Hello, But also we can see that if:     Why Mathcad (at least Prime 8 ) does not want to show all solutions of an equation?  

We have MathCad Subscription and Mathcad prime SDK.Our licensing changed to a floating license but I have no idea how to configure this on FlexNet.the FAQ's are all so confusing if someone could point me to the appropriate one I would be so grateful.

Hello,Is it possible to make such kind of 3D plots in Mathcad Prime?Those plots from below are only some examples to give you an idea of ​​what I mean, but if you have other examples then they are welcome.      

Hello,1. Given the below points: (x1,y1), (x1,y2), (x2,y1), (x2,y2), how to make a rectangle in Mathcad Prime based on this points?   2. Given the below points: (x1,y1), (x2,y1), (x3,y2), how to make a triangle in Mathcad Prime based on this points?

Hello,  I am using Mathcad Prime 7, paid version and i want to copy and paste text and math into Word. I have tried simply selecting the items and copying them, however they don't look good, some text falls off as the text boxes seem to shrink both lengthwise and heightwise as shown here in the screenshot. As i have loads of pages to import, i don't want to check and enlarge each textbox individually. I would like to know how to fix this without having to result to making screenshots, exporting to PDF etc etc..  Thank you!    

I get an error message saying my variable "t" must be a scalar or a matrix.  I believe i loaded it as a scalar.  What did I do wrong?I am using Mathcad Mathcad Prime 9.0.0.0.Jack Smith 

Hi all, I am aware that this topic has been covered many times before, but I am a bit puzzled on how to achieve an iterated solve block in Mathcad Prime 4.0. I cannot attach my worksheet, unfortunately, but I will attach an image to illustrate what I am trying to do below.   I have one equation in terms of x, and one in terms of i. I want to find all the (x,i) points where the values of these functions are equal. The way I thought to do it was to somehow nest a solve block in a for loop.  I've seen previous posts that use the "Find" function, but I guess in prime, I can only use the "find" function inside a solve block.  The problem is that I'm looking for pretty good resolution in my data points. This is why in the attached image, i is a range variable going from 0 - 1200 mA. My end goal is to get a matrix of x values that correspond to those i values. I truly appreciate the help, and I hope I'm not beating a dead horse too much! Thank

Hello,          

Hello,The right endpoints of the five intervals are:   where i = 1, 2, 3, 4, 5. The width of each rectangle is: and the height of each rectangle can be obtained by evaluating f(x) at the right endpoint of each interval.     How to create the below rectangles in Mathcad Prime (8)?
