To create a custom colormap, specify map as a three-column matrix of RGB triplets where each row defines one color. An RGB triplet is a three-element row vector whose elements specify the intensities of the red, green, and blue components of the color. The intensities must be in the range [0,1]. For example, this matrix defines a colormap containing five colors.
map = [0.2, 0.1, 0.5
0.1, 0.5, 0.8
0.2, 0.7, 0.6
0.8, 0.7, 0.3
0.9, 1, 0];
