mexErrMsgTxt
Issue error message and return to the MATLAB prompt
subroutine mexErrMsgTxt(error_msg) character*(*) error_msgerror_msg
Character
array containing the error message to be displayed.
mexErrMsgTxt
to write an error message to the MATLAB window. After the error message prints, MATLAB terminates the MEX-file and returns control to the MATLAB prompt.
Calling mexErrMsgTxt
does not clear the MEX-file from memory. Consequently, mexErrMsgTxt
does not invoke any registered exit routine to allocate memory.
If your application calls mxCalloc
or one of the mxCreate
routines to create mxArray
pointers, mexErrMsgTxt
automatically frees any associated memory allocated by these calls.
