Scaled vector addition

 

Y

REAL or COMPLEX array, minimum length

 

 

(N - 1) x incy + 1.

 

 

INCY

Increment for the array y. A vector y having component

 

 

yi, i = 1,..., n, is stored in an array Y() with increment

 

 

argument incy. If incy > 0 then yi is stored in

 

 

Y(1 + (i - 1) x incy). If incy < 0 then yi is stored in

 

 

Y(1 + (N - i) x incy). incy = 0 is an illegal value.

 

INCW

Increment for the array w. A vector w having

 

 

component wi, i = 1,..., n, is stored in an array W() with

 

 

increment argument incw. If incw > 0 then wi is stored

 

 

in W (1 + (i - 1) x incw). If incw < 0 then wi is stored in

 

 

W(1 + (N - i) x incw). incw = 0 is an illegal value.

Output

W

The result of the addition of the two scaled vectors, x

 

 

and y. REAL or COMPLEX array, minimum length

 

 

(N - 1) x incw + 1.
