Use of discrete colors in contourf and pcolor with colorbar

To set specific colors to the filled contours and pcolor plots and then to set the correct colorbar.

There are three three files
Recolor_pcolor.m , Recolor_contourf.m and colorbar_levels.m
The Recolor_pcolor/Recolor_contourf functions re-assign the specific colors to specific levels. The required colormap must be assigned to the pcolor/contourf plots before calling this function. The number of colors in the colormap must be one plus the length of levels.
While making the contourf plot make it on [min(data) Levels] levels. In addition to that keep max(Levels) <max(data)
After plotting pcolor set the caxis on bounds [min(data) max(Levels)]
All comments are welcome.
Thanks
