mwArray RowIndex() const

Return array containing row indices of each element in this array.

C++ syntax

#include <stdio.h>
#include "mclcppclass.h"
mwArray a(1, 1, mxDOUBLE_CLASS);
mwArray rows = a.RowIndex();

Arguments

None

Return value

An mwArray containing the row indices.

Description

Returns an array of type mxINT32_CLASS representing the row indices (first dimension) of this array. For sparse arrays, the indices are returned for just the non-zero elements and the size of the array returned is 1-by-NumberOfNonZeros(). For nonsparse arrays, the size of the array returned is 1-by-NumberOfElements(), and the row indices of all of the elements are returned.
