Thanks Jason,
now I tried to implement such a True/False function in order to
multiply it with the actual plot function to carve out the wanted plot
region.
Below I defined the function as a callable object as requested by the
plot command.
In a print test the function works well.
But when used in the plot3d function all I get is a flat plane at +1
height instead of a carved out rectangle at height +1 and a frame
around it at 0 height.
What is wrong? Is f in plot3d not evaluated for each set of
parameters?
