What are the Z value(s) set for points outside the polygonal boundary of 
the ROI?
Have they already a special value, or a specific range?

Otherwise, as answered by Bruno, you may use an external in_polygon() 
boolean function.
There is this one: https://fileexchange.scilab.org/toolboxes/121000
But it is not vectorized (easy to do).
Some vectorized (so much faster) version already exists in an external 
toolbox,
but i don't remember which one..
