Hello

I have a four points with [x y z] global coordinates:

A=[0 0 0]; 
B=[10 0 0];
C=[10 10 1];
D=[0 10 0];

X vector for left side is:

X_L=[A(:,1):1:B(:,1)]

X vector for right side is:

X_R=[D(:,1):1:C(:,1)]

Y vector for bottom is:

Y_B=[A(:,2):1:D(:,2)]

Y vector for top is:

Y_T=[B(:,2):1:C(:,2)]

How to create mesh/matrix with z global value?

In future I want to use more points.

It might help if you post all your code together, including your use of the mesh and meshgrid functions that are not working for you.

I solve problem with using 2-D look up table. This solution allow to use points coordinates.
