SUBROUTINE SCOPY(N,SX,INCX,SY,INCY) copies one real vector SX into another SY. SY:= SX. N Input, INTEGER N, number of elements in the vectors. SX Input, REAL SX(N), real vector to be copied. INCX Input, INTEGER INCX, increment between elements of SX. For contiguous elements, INCX = 1. SY Output, REAL SY(N), real result vector. INCY Input, INTEGER INCY, increment between elements of SY. For contiguous elements, INCY = 1.
