Use of built-in colormaps:

MATLAB has built-in colormaps, it is also possible to generate others by using combinations of any colors. For illustration, the following generates a customized colormap with only three colors: black, white, & red. This is then set to be the present colormap by passing the color map matrix to the colormap function. Then, a 40× 40 matrix of arbitrary integers in the range from 1 to 3 (as there are just 3 colors) is generated, and that is passed to the image function; the results are as shown in figure:

>> mycolormap = [0 0 0; 1 1 1; 1 0 0]

mycolormap =

0 0 0

1 1 1

1 0 0

>> colormap(mycolormap)

>> mat = randint(40,40,[1 3]);

>> image(mat)
