There are many small irritations in MATLAB, such as the lack of native LaTeX support for tick labels on the axes in a figure and (at least on the current Mac OS X installation, v. R2011b) failure to support all the native Mac services, such as the "don't save" key-binding when closing a window or normal filesystem windowing when print-to-file is selected. I do not see a way to save color figures to .ps files, either.
But here is one helpful thing. For study of MATLAB's syntax on a level a
little deeper than what is supplied in the various guides, after
finishing a figure, use the menu item
File -> Generate Code... to see
how MATLAB really describes the figure you have produced. It is
instructive to be able to see various efficiencies an inefficiencies
introduced, as well as an explicit statement of some of the defaults you
have unknowingly used.
