Function Documentation

kernel void mult	(	global float4 *	a,
		global float4 *	b,
		global float4 *	out
	)

Multiplies two input arrays together, element-wise.

Note

The global workspace should be one-dimensional. The x dimension of the global workspace, \( gXdim \), should be equal to the number of elements in the array, M x N, divided by 4. That is, \( \ gXdim = M*N/4 \). The local workspace is irrelevant.

Parameters

[in]	a	first operand. Input array of float elements.
[in]	b	second operand. Input array of float elements.
[out]	out	product. Output array of float elements.

kernel void pown_	(	global float4 *	in,
		global float4 *	out,
		int	n
	)

Raises an array to an integer power, element-wise.

Note

The global workspace should be one-dimensional. The x dimension of the global workspace, \( gXdim \), should be equal to the number of elements in the array, M x N, divided by 4. That is, \( \ gXdim = M*N/4 \). The local workspace is irrelevant.

Parameters

[in]	in	input array of float elements.
[out]	out	output array of float elements.
[in]	n	power to which to raise the array.
