sswap
Interchange two single-precision floating-point vectors.
Installation
npm install @stdlib/blas-sswap
Usage
var sswap = require( '@stdlib/blas-sswap' );
sswap( x, y )
Interchanges two single-precision floating-point vectors x
and y
.
var Float32Array = require( '@stdlib/array-float32' );
var array = require( '@stdlib/ndarray-array' );
var x = array( new Float32Array( [ 4.0, 2.0, -3.0, 5.0, -1.0 ] ) );
var y = array( new Float32Array( [ 2.0, 6.0, -1.0, -4.0, 8.0 ] ) );
sswap( x, y );
var xbuf = x.data;
// returns <Float32Array>[ 2.0, 6.0, -1.0, -4.0, 8.0 ]
var ybuf = y.data;
// returns <Float32Array>[ 4.0, 2.0, -3.0, 5.0, -1.0 ]
The function has the following parameters:
- x: a 1-dimensional
ndarray
whose underlying data type isfloat32
. - y: a 1-dimensional
ndarray
whose underlying data type isfloat32
.
Notes
Examples
var discreteUniform = require( '@stdlib/random-base-discrete-uniform' );
var Float32Array = require( '@stdlib/array-float32' );
var array = require( '@stdlib/ndarray-array' );
var sswap = require( '@stdlib/blas-sswap' );
var x = array( new Float32Array( 10 ) );
var y = array( new Float32Array( 10 ) );
var rand1 = discreteUniform.factory( 0, 100 );
var rand2 = discreteUniform.factory( 0, 10 );
var i;
for ( i = 0; i < x.length; i++ ) {
x.set( i, rand1() );
y.set( i, rand2() );
}
console.log( x.data );
console.log( y.data );
sswap( x, y );
console.log( x.data );
console.log( y.data );
