Improve performance of exception-free S-functions
Improves performance of S-functions that do not use mexErrMsgTxt, mxCalloc,
or any other routines that can throw an exception. An S-function is
not exception free if it contains any routine that, when called, has
the potential of long-jumping out of a block of code and into another
scope. See Exception Free Code for
more information.
See vsfunc.c for
an example.
