Detailed Description

Generate an array with [0, n-1] values along the a specified dimension and tiled across other dimensions.

Examples:

 
    // Generates an array of [0, 4] along first dimension
    array a = range(dim4(5));          // a = [0,
                                       //      1,
                                       //      2,
                                       //      3,
                                       //      4]
 
    // Generates an array of [0, 4] along first dimension, tiled along second dimension
    array b = range(dim4(5, 2));       // b = [0, 0,
                                       //      1, 1,
                                       //      2, 2,
                                       //      3, 3,
                                       //      4, 4]
 
    // Generates an array of [0, 2] along second dimension, tiled along first dimension
    array c = range(dim4(5, 3), 1);    // c = [0, 1, 2,
                                       //      0, 1, 2,
                                       //      0, 1, 2,
                                       //      0, 1, 2,
                                       //      0, 1, 2]

af_range()

AFAPI af_err af_range	(	af_array *	out,
		const unsigned	ndims,
		const dim_t *const	dims,
		const int	seq_dim,
		const af_dtype	type
	)

C Interface to generate an array with [0, n-1] values along the seq_dim dimension and tiled across other dimensions of shape dim4.

Parameters
