Figure Properties - SERC

If you specify color using C, fill3 scales the elements of C by the axes property
CLim, which specifies the color axis scaling parameters, before indexing the
current colormap.
If C is a row vector, fill3 generates flat-shaded polygons and sets the
FaceColor property of the patch objects to 'flat'. Each element becomes the
CData property value for the respective patch object.
If C is a column vector or a matrix, fill3 generates polygons with interpolated
colors and sets the patch object FaceColor property to 'interp'. fill3 uses a
linear interpolation of the vertex colormap indices when generating polygons
with interpolated colors. The elements in one column become the CData
property value for the respective patch object. If C is a column vector, fill3
replicates the column vector to produce the required sized matrix.
Examples Create four triangles with interpolated colors.
X = [0 1 1 2;1 1 2 2;0 0 1 1];
Y = [1 1 1 1;1 0 1 0;0 0 0 0];
Z = [1 1 1 1;1 0 1 0;0 0 0 0];
C = [0.5000 1.0000 1.0000 0.5000;
1.0000 0.5000 0.5000 0.1667;
0.3330 0.3330 0.5000 0.5000];
