# icopy.f(3)

## NAME

TESTING/LIN/icopy.f

## SYNOPSIS

### Functions/Subroutines

subroutine **icopy** (n, sx, incx, sy, incy)\
 **ICOPY**

## Function/Subroutine Documentation

### subroutine icopy (integer n, integer, dimension( \* ) sx, integer incx, integer, dimension( \* ) sy, integer incy)

**ICOPY**

**Purpose:**

```
!>
!> ICOPY copies an integer vector x to an integer vector y.
!> Uses unrolled loops for increments equal to 1.
!>
```

**Parameters**

*N*

```
!>          N is INTEGER
!>          The length of the vectors SX and SY.
!>
```

*SX*

```
!>          SX is INTEGER array, dimension (1+(N-1)*abs(INCX))
!>          The vector X.
!>
```

*INCX*

```
!>          INCX is INTEGER
!>          The spacing between consecutive elements of SX.
!>
```

*SY*

```
!>          SY is INTEGER array, dimension (1+(N-1)*abs(INCY))
!>          The vector Y.
!>
```

*INCY*

```
!>          INCY is INTEGER
!>          The spacing between consecutive elements of SY.
!>
