Returns a vector containing the results of performing a fused cross multiply-add operation for each corresponding set of elements of the given vectors.
d=vec_xmadd(a, b, c)The following table describes the types of the returned value and the function arguments.
| d | a | b | c |
|---|---|---|---|
| vector4double | vector4double | vector4double | vector4double |
The values of the elements of the result are the product of the values of the first and the third elements of a and the elements of b, added to the values of the corresponding elements of c.
d[0] = ( a[0] × b[0] ) + c[0]
d[1] = ( a[0] × b[1] ) + c[1]
d[2] = ( a[2] × b[2] ) + c[2]
d[3] = ( a[2] × b[3] ) + c[3]a = ( 1.0, 0.0, 3.0, 0.0)
b = ( 5.0, 10.0, 15.0, 20.0)
c = (10.0, 10.0, 10.0, 10.0)
d: (15.0, 20.0, 55.0, 70.0)
