Input

• a - S3L internal array handle for the parallel 1D or 2D array of real or complex type whose autocorrelation is to be computed.

• c - S3L internal array handle for the parallel 1D or 2D array of the same type as A, used to store the result of the autocorrelation. Its extents along each axis must be at least equal to two times the corresponding extent of A minus 1.
