mwArray RowIndex() const Purpose Return array containing row indices of each element in 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. D-67
