coloindex

calculates the index for use with direct color indexing with multiple colormaps

Description

Calculates the index for direct index
color mapping with multiple colormaps

USAGE:
  ic = colorindex(z,cmap,clim)

DESCRIPTION:
  Calculates the index for use with
  direct index color mapping
  This allows for different colormaps
  on the same figure.
  This is done by appending new colormaps
  to the figure's colormap and saving the
  lengths of each subcolormap to calculate
  the corresponding color index.
  The index can be used as follows
  image(ic,'CdataMapping','Direct')
  surf(ic,'CdataMapping','Direct')
  contour(ic,'CdataMapping','Direct')
  etc.
  The only problem with this is that the
  matlab colobar function cannot be used.
  Instead you can use colorbardi.m

INPUT:
  z - Data
  cmap - Colormap
  clim - Pseudocolor axis scaling limits

OUTPUT:
  ic - Color Index
