Perform Matrix Cross-product with a GPU

Performs matrix cross-product using a GPU. This function is merely a couple of wrappers for the CUBLAS cublasSgemm function.

	gpuCrossprod(a, b=NULL)

`a`	a matrix of floating point values.
`b`	a matrix of floating point values. A null value defaults to 'a'.

A matrix of single precision floating point values. The matrix is the cross-product of arguments 'a' and 'b', i.e., t(a) * b.

matA <- matrix(runif(3*2), 3, 2)
matB <- matrix(runif(3*4), 3, 4)
gpuCrossprod(matA, matB)
