Hi.  Making progress.  Caveat for what follows: the last version of Matlab I 
used was like 6 or 7, I think - it's been a little while - so for all I know, 
the colormap manipulation API I've been able to discover in the current MPL 
does correspond closely to the same thing in the current Matlab.  That said, 
said MPL colormap API is much more "powerful" (and consequently complicated) 
than I need, at least for right now. :-)  Is there a set of tools I'm not 
finding, or perhaps a third-party add-on, that enables more Matlab-like 
colormap manipulation?  For example, I'm use to a (Matlab) colormap simply 
being an Nx3 array of N RGB triples (or at least that's the API), which one can 
then process using standard array operators (+, *, etc.), methods (transpose, 
flipud, fliplr, etc), etc. and create and apply new colormaps by simply saying 
"colormap = <new N x 3 array>" - are there tools which enable this manner of 
manipulating MPL's colormap class instances?  Or
a "built-in" API to these that I'm not finding?  Thanks!

DG

PS: In case this is relevant, I'm using the OO API, not pylab.  Thanks again.
