d = vec_meadd(a, b, c)Returns a vector containing a double element-sized results of performing a multiply-and-add operation for each of the even-indexed elements on the given vectors. The value of each element is the value of the double element-sized of the product of the values of the even-indexed elements of a and b, added to the value of the corresponding element of c.
