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?

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.

I had not found this documentation. Thanks for that. But still: How can I suppress the solution/result to be the 3rd Dimension and plot the solution in a 2D-plot and the value of the solution/result is defined by the Color? I have the x- and z-Coordinate. y-Coordinate is fixed (since slice-view) and the value of the interpolate data, e.g. temperature, is defined by the Color.

The same view as pdeplot gives

Take a look at the examples in Contour Slices Through a 3-D Solution documentation page.
Particularly the function interpolateSolution might be relevant to you.
