Octave-Forge: MissingMatlabFunctions

Functions in Matlab 2008a Missing from Octave

This list has not been fully checked, and it was generated on a computer with all the octave-forge packages installed, so it will not list functions that are in Octave-Forge that need to be moved to Octave.

The categorization was done by quick inspection. Please feel free to move functions between categories as you think is appropriate.
