Detailed Description

Access one or more slices of an array.

A slice is a 2D cross section of a volume or 3D array. It is synonymous with channel of an image or plane of a volume.

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

Function Documentation

array slice ( int index ) const

inline

Access slice index to form a matrix (plane of a volume, channel in an image)

float f[] = {1,2,3,4,5,6,7,8};
array a(2,2,2,f); //a=[1 3][5 6]
                  //  [2 4][7 8]
array b = a.slice(1); //b = [5 6]
                      //    [7 8]

Parameters

[in] index slice index

Returns: Returns an array of size dims(0) x dims(1) x 1

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

array slices	(	int	first,
		int	last
	)		const

inline

Access slices first through last to form a matrix (inclusive)

Parameters

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

Returns: Returns an array of size dims(0) x dims(1) x (last - first + 1)

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