keepfield

01 Mar 2005 (Updated 03 Mar 2005)

Keep specified fields of a structure, discarding other fields.

File Information
Description	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.
