The v?MulByConj function performs element by element multiplication of vector a element and conjugated vector b element.
Specifications for special values of the functions are found according to the formula
MulByConj(x1+i*y1,x2+i*y2) = Mul(x1+i*y1,x2-i*y2).
Overflow in a complex function occurs (supported in the HA/LA accuracy modes only) when x1, x2, y1, y2 are finite numbers, but the real or imaginary part of the exact result is so large that it does not fit the target precision. In this case, the function returns ∞ in that part of the result, raises the OVERFLOW exception, and sets the VML Error Status to VML_STATUS_OVERFLOW.
