Single-precision complex input vector with a stride of 1.
Single-precision real input-output vector with a stride of 1.
Number of elements to process.
This function computes the autospectrum of complex input vector
A: it multiplies elements of
A by their complex conjugates, yielding the sums of the squares of the complex and real parts: (x + iy) (x - iy) = (x*x + y*y). The results are added to real input-output vector
C should contain valid data from previous processing or should be initialized according to your needs before calling this function.
