Syntax

map = copper

Returns the colormap with as many rows as the current colormap.

map = copper(m)

Returns an m-by-3 colormap.

Description

Each row of the result is one color, ordered from the lowest to the highest data value. Pass the matrix to colormap to apply it, as in colormap(copper(64)). A smaller m gives visibly distinct bands, which suits contour-like displays.

Input arguments

m: Number of colors. The default is the number of rows of the current colormap.

Output arguments

map: Matrix with m rows and three columns. Each row is an RGB triplet with values between 0 and 1.

Example

Three colors

copper(3)
