I have Mathcad Prime 3.0 installed and have a floating CU license, but maintenance has expired in 2014. I was issued a new license to remove the expiration dates, but still when I open Mathcad Prime, it only opens express. Any ideas what might be going wrong?

Hello Guys,i got a question, maybe im doing something wrong but....When i try to use the function boxplot(Data) the Q1 and Q3 are wrong. But the Median is right.Example:Q1 = 1.25 and Q3=3.75BUTQ1 should be 1.5 and Q3 should be 3.5, am i wrong?Q1= (1+2)/2 = 2.5 and Q3=(3+4)2=3.5If you want to see it in Mathcad, its in the AttachThanks and regardsSamuel

"Failed to configure license for PTC Mathcad Prime 3.1: '.', hexadecimal value 0x00, is an invalid character. Line 6, position 1."This is the error message I always get whenever I try to configure my license for Mathcad 3.1, or any other kind of Mathcad product. I will even put up a random file name and it will give me the same message. Please help

   Hello Everyone.   1i*ln(1/[e^pi]^1i) simplify ==> -pi  and  1i*ln(1/[e^pi]^1i) = -pi simplify ==> 0 ( Could apply "simplify" in this case ? )           Thanks in advance.                 Regards.

HiI have seen a few conversations about plotting 3D meshes in Prime using plot 3D. There is a very good discussion  where a ply file was used to generate a dolphin mesh. I cannot comvert this to a Prime format and the ply file format is missing.What I want to do seems simple but for whatever reason, Mathcad cannot simply plot a 3D wireframe based on the start coordinates of a line and the end coordinates of a line.It seems that it is only possible to draw a continuous 3D line from a plot.I understand for instance CreateMesh function creates a mesh for format in the 3Dplot but it looks like the mesh edges have to be continuous.This seems crazy. I have tried collapsing or using the same node coordinates of node 2 for matrix entries for third and 4th nodes but that does not seem to work.I understand Mathcad uses quad faces/facettes. So, I had thought if I collapse three edges to form a single line and feed the format of the quad face into 3d plot that would work but it doesn't.How ca

Dear all,I would like to solve a plate in the figure by solve  system of differential equation IN MATHCAD 15 (1 for the internal plate and 1 for the external plate/ring).Can anyone help me? I know the various boundary condition but I don't know how can I set it.Best regardsStefano

Will MathCad Prime 4.0 support subscripts and superscripts in text (without resorting to workarounds). Mathcad 14 and 15 did it elegantly.Thanks

How do we without?

Hello all,I have two questions regarding the use of the 2d interpolation function:As you can see in the attached file, I cannot display the x-axis in the right way.How can I use the fit function for the get the results from an input array?Thank.you very much!Enrico

Hi, guysI want to plot the function:f(x,y) = x^2 + y^2 +x*y - 3600, bounded with f(x,y) <=0;Just like the graph shown below:The figure is plotted with ezplot in Matlab.function a=elp1(x,y)     a=x.^2+y.^2-60^2-x.*y;endfigure(1)h1=ezplot('elp1',[-90,90,-90,90]);So far I haven't figured out an alternative in Mathcad that can do this.Could you help me with some ideas?Thank you very much!BestShawn

Well, I'd eagerly been awaiting Prime 4.0 so I could like break my find functions that run off the page.  Alas, that new capability only works if you have a +,-,* or /.  So, I'm wondering if there are any tricks that might work.  I haven't been able to find any.  Thanks,

Hi, I need assistance debugging a program to build  a Z-score table with the intention to reproduce in Mathcad a z-score table very similar to the one that we could create with an excel spreadsheet. This just for fun!See attached files.Thank youjuan

Hello Everyone,I hope everyone is going to have a great week ahead. I am having a problem with a if else statement. Although my summation is matching from both sides but it is evaluating as  "False" in output. It would be very nice if you can help me out with it.ThanksFaisal
