I would like to translate TriScatteredInterp from Matlab to C# and I do these operations but they don’t work.
  1. I create "interpolazione.m" file on my desktop
  2. I press buttons "Desktop -> MATLAB Coder: MEX Function"
  3. I create "interpolazione.prj" file, I add "interpolazione.m" file in "Entry-Point Files" and I press "Build" button.
I get the following error message:
coder interpolazione.prj Could not locate build the MEX file compiler options mexopts.bat. Run mex-setup to select the MEX compiler and create the MEX options file. Use codegen help for more information on using this command.
The code that I would like to translate is this:
X=[0,1,2,0,1,2,0,1,2]';
Y=[0,0,0,1,1,1,2,2,2]';
Z=[0,0,0,1,1,1,2,2,2]';
x=[1.5,1.6,1.7];
y=[1.5,1.1,11.0];
F = TriScatteredInterp(X,Y,Z);
z = F(x,y)
Thanks for the help

Hi,
besides of that error message. Don't even try to generate a mex file from that code because TriScatteredInterp isn't supported for code generation:

Consider using MATLAB Builder NE in order to generate a .NET DLL out of your code which than can be used in C# directly.
As far as I know, MATLAB uses the qhull library under the hood. Maybe the library itself is enough for you:

Thanks for your help. TriScatteredInterp is equal to Qhull or the first used in Matlab is better?
