This command is not giving me the full spectrum. The spectrum by default is
in gray. Is there a way to change it to RGB.

Calling 'colormap hot' first should work.

You can put this in your .octaverc file.

The default is in %HOMEDRIVE%:%HOMEPATH%/.octaverc

This is probably 'C:/Documents and Settings/<username>/.octaverc', but you can type the following from octave to be sure:

   [getenv('HOMEDRIVE'),':',getenv('HOMEPATH')]
