### Functions/Subroutines

subroutine **dcopy** (n, dx, incx, dy, incy)**DCOPY**

## Function/Subroutine Documentation

### subroutine dcopy (integer n, double precision, dimension(*) dx, integer incx, double precision, dimension(*) dy, integer incy)

**DCOPY**

**Purpose:**

DCOPY copies a vector, x, to a vector, y. uses unrolled loops for increments equal to 1.

**Parameters***N*N is INTEGER number of elements in input vector(s)

*DX*DX is DOUBLE PRECISION array, dimension ( 1 + ( N - 1 )*abs( INCX ) )

*INCX*INCX is INTEGER storage spacing between elements of DX

*DY*DY is DOUBLE PRECISION array, dimension ( 1 + ( N - 1 )*abs( INCY ) )

*INCY*INCY is INTEGER storage spacing between elements of DY
