integer value, the colormap size.
It not provided for continuous/sequential/diverging colormaps, the default size is the size of the current (See gcf()) figure colormap, or the size of the default (See gdf()) figure colormap (if no figure is opened).
It not provided for discrete/qualitative colormaps, the default size is the size of the base pattern (fixed colors) depending on the colormap type (see below in colormaps description).
matrix with 3 columns [R,G,B].
All these functions provide predefined continuous/sequential/diverging colormaps for Scilab graphics:
Computes a colormap with n colors varying from red through orange to yellow.
Computes a gray colormap with n colors with a light blue tone.
Computes a colormap with n colors varying from cyan to magenta.
Computes a colormap with n colors varying from black to a light copper tone.
Computes a colormap with n gray colors varying linearly from black to white.
Computes a colormap with n hot colors varying from red to yellow.
Computes a colormap with ncolors. This colormap varies the hue component of the
hsv color model. The colors begin with red, pass through yellow, green, cyan, blue, magenta, and return to red.
The map is particularly useful for displaying periodic functions.

Computes a colormap with n colors varying from magenta to yellow.
Computes a colormap with n colors varying from green to yellow.
Computes a colormap with n colors varying from blue, lightblue, green, yellow, orange then red (quite similar to jet but perceptually uniform).
Computes a completely white colormap with n colors.

Computes a sequential single-hue red colormap with n colors.
Computes a diverging multi-hue spectral colormap with n colors.
Computes a diverging multi-hue colormap with n colors varying from red to blue.
Computes a diverging multi-hue colormap with n colors varying from red to grey hue.
