delvarmat

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
