Each of these functions computes the dot product of two vectors, defined by the following equation:
Z = X . Y*
where Y* is the conjugate of the Y vector.
For real data, the following equation is used:
n-1 z[0] = SUM (x[i]*y[i]) i=0
For complex data, the following equation is used:
n-1 z[0] = SUM (x[2*i]*y[2*i] + x[2*i + 1]*y[2*i + 1]) i=0 n-1 z[1] = SUM (x[2*i + 1]*y[2*i] - x[2*i]*y[2*i + 1]) i=0
Each of the functions takes the following arguments:
z
x
y
n
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
