CHECK_MEX_COMPILED Check if mex file is compiled for system.

SYNTAX

CHECK_MEX_COMPILED(SOURCE_FILE)
CHECK_MEX_COMPILED(OPTIONS,SOURCE_FILE)

DESCRIPTION

CHECK_MEX_COMPILED(SOURCE_FILE) checks whether a mex source file SOURCE_FILE is compiled for the current operating system OR whether the source file has been modified since it was compiled. It is compiled if it does not pass these tests (to the same directory as the source file). SOURCE_FILE must be a string that is the name of a source file on the MATLAB search path.

CHECK_MEX_COMPILED(OPTIONS,SOURCE_FILE) passes the script switches in OPTIONS to the mex compiler, one argument per switch.

USAGE EXAMPLE

% check function compiled, with useful debugging info,
% and with large-array-handling API
check_mex_compiled('-v','-g','-largeArrayDims','myfunction.c')
