The row indexing functions return elements located in the specified row(s).

If the array is 3-dimensional or higher, then the specified rows from all slices are returned.

Function Documentation

array row ( int index ) const

inline

Access row index to form row vector.

\code
float f[] = {1,2,3,4};
array a(2,2,f); //a=[1 3]
                //  [2 4]
array b = a.row(1); //b = [2 4]

Parameters

[in] index row index

Returns: Returns an array of size 1 x dims(1) x dims(2)

Note: Cannot be used in gfor. Use array(index, span, span) instead.

array rows	(	int	first,
		int	last
	)		const

inline

Access rows first through last to form a matrix (inclusive).

float f[] = {1,2,3,4,5,6};
array a(3,2,f); //a=[1 4]
                //  [2 5]
                //  [3 6]
array b = a.rows(1,2); //b=[2 5]
                       //  [3 6]

Parameters

[in]	first	beginning row index
[in]	last	end row index

Returns: Returns an array of size (last - first + 1) x dims(1) x dims(2)

Note: Cannot be used in gfor. Use array(seq(first, last), span, span) instead.
