INTEGER*8 INCW, INCV, INCU, N
COMPLEX*16 ALPHA, R, W( * ), V( * ), U( * )
SUBROUTINE F_ZAXPY_DOT ( N, ALPHA, W, INCW, V, INCV, U, INCU )
Input N Number of elements of vector.
ALPHA The scalar ALPHA.
W REAL or COMPLEX array, minimum length
(N - 1) x |incw| + 1.
INCW Increment for the array w. A vector w having
component w
i
, i = 1,...,n, is stored in an array
W() with increment argument incw. If incw > 0 then w
i
is stored in W (1 + (i - 1) x incw). If incw < 0 then w
i
is
stored in W(1 + (N - i) x |incw|).
incw = 0 is an illegal value.
