colormap

Set/get the RGB colormap of currently active figure

# Calling Sequence

    c = colormap(M)

## Parameters

M

- n by 3 matrix or a string

c

- n by 3 matrix

## Description

colormap(M) sets the current figure's colormap to M.

M = colormap() retrieves the current colormap. The values are in the range from 0 to 1. M is a m x 3 matrix. m is the number of colors. Color number i is given as a 3-uple M(i,1), M(i,2), M(i,3) corresponding respectively to red, green and blue intensity. For example, [0 0 0] is black, [1 1 1] is white, [1 0 0] is pure red, [.5 .5 .5] is gray, and [127/255 1 212/255] is aquamarine.

When M is a string, M can take the values

- 'hot', 'gray', 'copper', 'cool', 'bone', 'red','green', 'blue', jet'

The colormap is used by macros which produce pseudocolor patches, such as pcolor, tripcolor, surf, trisurf, surfl, trisurfl.

## Examples

    pcolor(rand(10,10));
    colormap gray
