NAME sscal - Compute y := alpha * y SYNOPSIS SUBROUTINE SSCAL (N, ALPHA, Y, INCY ) REAL ALPHA INTEGER INCY, N REAL Y( * ) #include <sunperf.h> void sscal(int n, float sa, float *sx, int incx) ; PURPOSE SSCAL - 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 sub- routine to have any visible effect. Unchanged on exit. ALPHA - REAL. On entry, ALPHA specifies the scalar alpha. Unchanged on exit. Y - REAL 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.
