Syntax
polcmap polcmap(ncolors) polcmap(ncolors,maxsat) polcmap(ncolors,huelimits,saturationlimits,valuelimits) cmap = polcmap(...)
Description
polcmap applies a random muted colormap to the current figure. The size of the colormap is the same as the existing colormap.
polcmap(ncolors) creates a colormap with the specified number of colors
polcmap(ncolors,maxsat) controls the maximum saturation of the colors. Larger maximum saturation values produce brighter, more saturated colors. If omitted, the default is 0.5.
polcmap(ncolors,huelimits,saturationlimits,valuelimits) controls the colors. Hue, saturation and value are randomly selected values within the limit vectors. These are two-element vector of the form [min max]
. Valid values range from 0 to 1. As the hue varies from 0 to 1, the resulting color varies from red, through yellow, green, cyan, blue and magenta, back to red. When the saturation is 0, the colors are unsaturated; they are simply shades of gray. When the saturation is 1, the colors are fully saturated; they contain no white component. As the value varies from 0 to 1, the brightness increases.
cmap = polcmap(...) returns the colormap without applying it to the figure.
