# rgb2hsv

## Purpose

Red-green-blue to hue-saturation-value conversion.

## Synopsis

    H = rgb2hsv(M)

## Description

`H = rgb2hsv(M)` converts an RGB colormap to an HSV colormap. Each map is a matrix with any number of rows, exactly three columns, and elements in the interval from 0 to 1. The columns of the input matrix, `M`, represent intensities of red, green, and blue respectively. The columns of the resulting output matrix, `H`, represent hue, saturation, and value, respectively.
