mxIsCell
True if a cellmxArray
#include "matrix.h" bool mxIsCell(const mxArray *array_ptr);array_ptr
true if array_ptr points to an array having the class mxCELL_CLASS; otherwise, returns false.
Use mxIsCell to determine if the specified array is a cell array.
Do not confuse a cell array with a cell element. Remember that a cell array contains various cell elements, and that most cell elements are not cell arrays.
Consider a MEX-file that expects its first input argument to be a cell array. If it is not a cell array, the MEX-file issues an error message.
void
mexFunction(int nlhs,mxArray *plhs[],int nrhs,const mxArray
*prhs[])
{
if (mxIsCell(prhs[0])) {
/* ... Yes, it is a cell array. */
}
else /* No, this is not a cell array. */
mexErrMsgTxt("You must specify a cell array.");
}
For an additional example, see mxIsCell.c in the mx subdirectory of the examples directory.
