Hey Santiago ,
As per my understanding, you want to change the ‘FaceColor’ property of pdegplot and pdeplot3D plot figures. You can not change the ‘FaceColor’ property as an input argument to the "pdegplot" or "pdeplot3D" . You can refer to the following document to see the list of valid name-value pair arguments that can be passed as input to "pdegplot" and "pdeplot3D" :
So, to change any property in the plot, first store the plot in a handle and set value to that property using dot method on the handle. For example,
radiusE = 230;
gm = multisphere(radiusE);
model = createpde;
model.Geometry = gm;
p = pdegplot(model,'CellLabels','on','EdgeLabels','on'); %store the plot in a handle (here, it’s p)
p % Here, you can see all the plot properties
p.FaceColor = [1 0 0]; %Now, you can set any [r g b] value to ‘FaceColor’ property
Do same for the "pdeplot3D" in order to change the face colour.
Hope this helps!
