ML provides a useful function RMFIELD to remove specified field(s) from a structure, but no corresponding function to KEEP specified field(s), removing the rest. This function addresses that discrepancy.

ex.:
a = dir('*.m');
b = keepfield(a,{'name','date'});

This is an exceptionally short but useful piece of code.
