SYNOPSIS

SUBROUTINE CSSCAL (N, ALPHA, Y, INCY )

REAL    ALPHA

INTEGER INCY, N

COMPLEX Y( ∗ )

PURPOSE

CSSCAL - Compute y := alpha ∗ y where alpha is a scalar and y is an n-vector. 
 

PARAMETERS

N      - INTEGER. 
On entry, N specifies the number of elements in the vector.  N must be at least one for the subroutine to have any visible effect.  Unchanged on exit.

ALPHA  - REAL. 
On entry, ALPHA specifies the scalar alpha. Unchanged on exit.

Y      - COMPLEX array of DIMENSION at least
( 1 + ( m - 1 )∗abs( INCY ) ). On entry, the incremented array Y must contain the vector y. On exit, Y is overwritten by the updated vector y.

INCY   - INTEGER. 
On entry, INCY specifies the increment for the elements of Y. INCY must not be zero. Unchanged on exit.
