delvarmat

Removes a variable from a MAT-file

Description

 delvarmat Delete variable(s) from MAT-file
  STATUS = delvarmat(FILENAME,VARIABLE1,...) deletes the
  variable(s) from the MAT-file.
 
  STATUS = delvarmat(VARIABLE1,...) deletes the variable(s) from
  'matlab.mat'
 
  delvarmat returns 1(failure) if either the MAT-file doesn't exist in
  the current directory or if anyone of the listed variables don't
  exist in the MAT-file. delvarmat returns 0(success) otherwise.
 
  Note: If delvarmat can not find a particular variable in a MAT-file,
  even though it will return an error status, any variables already
  deleted will stay removed from the MAT-file.

Because the File Exchange doesn't allow for MEX-files, the C-code is included here to compile the code

To make it work with latest MATLAB, replace the matDeleteArray API call with matDeleteVariable API call (two places).
