mxClearLogical
Clear the logical flag
#include "matrix.h" void mxClearLogical(mxArray *array_ptr);array_ptr
Pointer to an mxArray having a numeric class.
mxClearLogical to turn off the mxArray's logical flag. This flag tells MATLAB that the mxArray's data is to be treated as numeric data rather than as Boolean data. If the logical flag is on, then MATLAB treats a 0 value as meaning false and a nonzero value as meaning true.
Call mxSetLogical to turn on the mxArray's logical flag.
See mxClearLogical.c in the mx subdirectory of the examples directory.
