mwArray ColumnIndex() const :: C++ Utility Library Reference (MATLAB Compiler)

MATLAB Compiler

mwArray ColumnIndex() const

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

C++ syntax

#include "mclcppclass.h"
mwArray a(1, 1, mxDOUBLE_CLASS);
mwArray rows = a.ColumnIndex();

Arguments

None

Return value

An mwArray containing the column indices.

Description

Returns an array of type mxINT32_CLASS representing the column indices (second 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 column indices of all of the elements are returned.
