Parameters

n	The size of the array to copy.
original	The array to be copied.

Returns

Copied array.

copy1DFromHostToHost()

void copy1DFromHostToHost	(	float *	oldLoc,
		float *	newLoc,
		size_t	n
	)

Copy a 1D array between two locations on host.

Parameters

oldLoc	The data to copy.
newLoc	Where to copy the data to.
n	The number of elements of the data to copy.

copy2DArray()

float** copy2DArray	(	size_t	n,
		size_t	m,
		float **	original
	)
