F_SAPPLY_GROT/F_DAPPLY_GROT/F_CAPPLY_GROT/F_ZAPPLY_GROT Apply plane rotation
Input N Number of elements of vector x.
C REAL scalar.
S REAL or COMPLEX scalar.
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.
Y REAL or COMPLEX array, minimum length
(N - 1) x |incy| + 1.
INCY Increment for the array y. A vector y having component
y
i
, i = 1,..., n, is stored in an array Y() with increment
argument incy. If incy > 0 then y
i
is stored in
Y(1 + (i - 1) x incy). If incy < 0 then y
i
is stored in
Y(1 + (N - i) x |incy|). incy = 0 is an illegal value.
Output X The updated array replaces the input—The plane
rotation of input X.
Y The updated array replaces the input—The plane
rotation of input Y.
