Hello to all,

I'm finishing to convert a module for linear regression that I used in Matlab. It takes an experimental matrix, and a response matrix perform a regression and a bit of plot and then give me 3 matrices that I need to plot response surface and leverage surface. For plotting leverage and response I need to create a kind of grid of point with another program. and at this point everything work fine (checked also in comparison with matlab). The problems come when I tri to plot it. For a step of 2 (not really a grid) it works with 30 steps everything crashes

so nste=2 work nstep=30 not

I attach the file that give no problems it's a module with included the matrix to be plotted with nstep=2 and also the problematic one. a function with the same name of the plot and the matrices that give the problems.

Every help would be greatly appreciated because if I fix it I can get rid of the regression program in matlab that i generally use really a lot in my everyday job
