**DESCRIPTION**

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
**PARAMETERS**

Each of the functions takes the following arguments:
z Pointer to the dot product of the two vectors.
x Pointer to the first element of the first source vector.
y Pointer to the first element of the second source vector.
n Number of elements in the vectors.
**RETURN VALUES**

Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
