PATCH Patch Graphics Function

Usage

This routine is used to create a patch object that can be plotting 2D and 3D surfaces. A patch is a polygon defined by the xyz coordinates of its vertices and optionally by the color at the vertices. There are several forms for the patch function:

  h = patch(X,Y,C,properties...)
  h = patch(X,Y,Z,C,properties...)
  h = patch(properties...)
  h = patch(V)

Where X, Y and Z are matrices or vectors of x, y or z coordinates and C is a matrix or vector of color values (the colormap for the current fig is applied).

Example

Here we generate a surface specifying all four components.

--> x = [ 0 1 0 1]';
--> y = [ 0 0 1 1]';
--> c = [ 1 1 1 ];
--> patch(x,y,c)
--> axis equal
--> view(3)
