MATLAB: Plot Slice of pdeplot3D

Question

Hello

I would like to plot a slice of the pdeplot3D(model,'ColorMapData',U) at a certain y-Coordinate, so that the plot has a x-z-View and the results U are still defined by the ColorMap.

I have tried the slice-function, but this results in an error (Maximum variable size allowed by the program is exceeded.) This is what I tried with interp3:

YCross=2;
Xgrid=linspace(1,10,50);
Zgrid=Xgrid;
UCross=interp3(p(1,:),p(2,:),p(3,:),U,Xgrid,YCross,Zgrid);

But I got the error: The grid vectors must contain unique points. I understand, that my p-vectors are not unique, but how to solve the Problem?

Answer 1

Did you look at the examples in the documentation? There is one example showing how to save memory by evaluating only where needed. I think, too, that those examples show how to avoid the problem of non-unique points.
