copy(3F)

NAME
     SCOPY, DCOPY, CCOPY, ZCOPY - Copies a real or complex vector into
     another real or complex vector

SYNOPSIS
     Real

        CALL SCOPY (n, x, incx, y, incy)

     Double precision

        CALL DCOPY (n, x, incx, y, incy)

     Complex

        CALL CCOPY (n, x, incx, y, incy)

     Double complex

        CALL ZCOPY (n, x, incx, y, incy)

IMPLEMENTATION
     IRIX systems

DESCRIPTION
     SCOPY/DCOPY copies a real vector into another real vector.

     CCOPY/ZCOPY copies a complex vector into another complex vector.

     These routines perform the following vector operation:

          y  <-  x


     where x and y are real or complex vectors.

     These routines have the following arguments:

     n     Integer.  (input)
           Number of elements to be copied.  If n <= 0, SCOPY and CCOPY
           return without any computation.

     x     Array of dimension (n-1) * |incx| + 1.  (input)
           SCOPY: Real array.
           DCOPY: Double precision array.
           CCOPY: Complex array.
           ZCOPY: Double complex array.
           Vector from which to copy.

     incx  Integer.  (input)
           Increment between elements of x.  If incx = 0, the results will
           be unpredictable.

     y     Array of dimension (n-1) * |incy| + 1.  (output)
           SCOPY: Real array.
           DCOPY: Double precision array.
           CCOPY: Complex array.
           ZCOPY: Double complex array.
           Result vector.

     incy  Integer.  (input)
           Increment between elements of y.  If incy = 0, the results will
           be unpredictable.

NOTES
     These routines are Level 1 Basic Linear Algebra Subprograms (Level 1
     BLAS).

     When working backward (incx < 0 or incy < 0), each routine starts at
     the end of the vector and moves backward, as follows:

          x(1-incx * (n-1)), x(1-incx * (n-2)), ..., x(1)

          y(1-incy * (n-1)), y(1-incy * (n-2)), ..., y(1)
