I want to make a 3D plot over a non-rectangular grid. I have vectors X=linspace(0,1,100) and Y=linspace(0,1,100) and I create the typical rectangular grid [x,y]=meshgrid(X,Y). Now I have matrix Z, and I can represent without problems mesh(x,y,Z). The thing is that I only know Z for points (x,y) with y less or equal than x, but never for (x,y) with y greater than x. Therefore, I would like to plot (x,y,Z) but showing only the triangular region of points (x,y) with x and y between 0 and 1 and y less or equal than x. How can I achieve this? Thanks!
