Extract a profile from 3D data

Hello,

How can we extract a 2d profile from a surface?

Input: point cloud N * 3 (X, Y, Z).

Output: profile (X, Z) for constant Y for example

Thank you!

If data is structured:

x = X(1,:) ; 
y = Y(1,:) ;  % give your required row value depending on y-value
z = interp2(X,Y,Z,x,y) ; 

If data is scattered:

F = scatteredInterpolant(X,Y,Z) ; 
% define your required (x,y)
z = F(x,y) ;
