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).
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)
