Matfig2PGF
Convert figures to PGF files that can be included in LaTeX documents.

A very, very nice contribution! Really wish I had found it earlier.
My only suggestion would be to implement something to check axes titles and legends to escape out LaTeX key characters. For example I have a plot with the title 'Voltage & Current against Time', which errors out when converted to pgf, as it needs to be 'Voltage \& Current against Time'.
