Control response of mexCallMATLAB
to errors
C Syntax
Arguments
trap_flag
Control flag. Currently, the only legal values are:
0 |
On error, control returns to the MATLAB prompt. |
1 |
On error, control returns to your MEX-file. |
Description
Call mexSetTrapFlag
to control the MATLAB response to errors in mexCallMATLAB
.
If you do not call mexSetTrapFlag
, then whenever MATLAB detects an error in a call to mexCallMATLAB
, MATLAB automatically terminates the MEX-file and returns control to the MATLAB prompt. Calling mexSetTrapFlag
with trap_flag
set to 0 is equivalent to not calling mexSetTrapFlag
at all.
If you call mexSetTrapFlag
and set the trap_flag
to 1, then whenever MATLAB detects an error in a call to mexCallMATLAB
, MATLAB does not automatically terminate the MEX-file. Rather, MATLAB returns control to the line in the MEX-file immediately following the call to mexCallMATLAB
. The MEX-file is then responsible for taking an appropriate response to the error.
Examples

in the mex
subdirectory of the examples
directory.
