F_SAXPBY/F_DAXPBY/F_CAXPBY/F_ZAXPBY Scaled vector accumulation
ALPHA The scalar ALPHA.
X REAL or COMPLEX array, minimum length
(N - 1) x |incx| + 1.
INCX Increment for the array x. A vector x having component
x
i
, i = 1,..., n, is stored in an array X() with increment
argument incx. If incx > 0 then x
i
is stored in
X (1 + (i - 1) x incx). If incx < 0 then x
i
is stored in
X (1 + (N - i) x |incx|). incx = 0 is an illegal value.
BETA The scalar BETA.
Y REAL or COMPLEX array, minimum length
(N - 1) x |incy| + 1.
