Description
contour3(Z) generates a 3-D contour plot illustrating the isolines of the matrix Z, where Z represents heights on the x-y plane.
The x and y coordinates in the plane correspond to the column and row indices of Z, respectively.
To specify the x and y coordinates for Z values, use contour3(X,Y,Z).
Example
f = figure();
[X,Y,Z] = sphere(50);
[M, C ]= contour3(X,Y,Z);
C.LineWidth = 3;
