surf

3D surface plot with colored faces.

Syntax

h = surf(Z)
h = surf(X, Y, Z)
h = surf(X, Y, Z, C, ...)

Description

Renders a 3D parametric surface from (X, Y, Z) grid data. With only Z, uses the row/column indices as X and Y. Optional C provides per-vertex color values; without C, the surface is colored by Z.

Examples

[X, Y] = meshgrid(-3:0.1:3);
Z = peaks(X, Y);
surf(X, Y, Z)
