d = vec_promote(a, b)Returns a vector with a in element position b. The result is a vector with a in element position b. This function uses modulo arithmetic on b to determine the element number. For example, if b is out of range, the compiler uses b modulo the number of elements in the vector to determine the element position. The other elements of the vector are undefined.
