cool

Cool colormap array

  • Cool colormap

Description

example

c = cool returns the cool colormap as a three-column array with the same number of rows as the colormap for the current figure (gcf). If no figure exists, then the number of rows is equal to the default length of 256. Each row in the array contains the red, green, and blue intensities for a specific color. The intensities are in the range [0,1], and the color scheme looks like this image.

Sample of the cool colormap

example

c = cool(m) returns the colormap with m colors.

Examples

collapse all

Plot a surface and assign the cool colormap.

surf(peaks);
colormap('cool');

Figure contains an axes object. The axes object contains an object of type surface.

Get the cool colormap array and reverse the order. Then apply the modified colormap to the surface.

c = cool;
c = flipud(c);
colormap(c);

Figure contains an axes object. The axes object contains an object of type surface.

Get a downsampled version of the cool colormap containing only ten colors. Then display the contours of the peaks function by applying the colormap and interpolated shading.

c = cool(10);
surf(peaks);
colormap(c);
shading interp;

Figure contains an axes object. The axes object contains an object of type surface.

Input Arguments

Number of colors, specified as a nonnegative integer. The default value of m is the number of colors in the current figure's colormap. If no figure exists, the default value is 256.
