Syntax

map = parula

Returns a parula colormap with the default number of rows.

map = parula(m)

Returns a parula colormap with m rows.

Description

Parula is the colormap that new figures start with. Its lightness rises steadily and its hue changes gradually, so equal steps in the data look like equal steps in color, and the map degrades gracefully in grayscale.

The returned matrix is interpolated from a fixed table of base colors to reach the requested length.

Input arguments

m: Number of colors, a nonnegative integer.

Output arguments

map: m-by-3 matrix of RGB values between 0 and 1.

Example

First and last colors

map = parula(2)
size(parula)

Output

map = 2×3

    0.2422    0.1504    0.6603
    0.9769    0.9839    0.0805
ans = 1×2
