j1

Compute the Bessel function of the first kind of order one.

The Bessel function of the first kind of order one is defined as

Bessel function of the first kind of order one

Usage

var j1 = require( '@stdlib/math/base/special/besselj1' );

j1( x )

Computes the Bessel function of the first kind of order one at x.

var v = j1( 0.0 );
// returns 0.0

v = j1( 1.0 );
// returns ~0.440

v = j1( Infinity );
// returns 0.0

v = j1( -Infinity );
// returns 0.0

v = j1( NaN );
// returns NaN

Examples

var randu = require( '@stdlib/random/base/randu' );
var j1 = require( '@stdlib/math/base/special/besselj1' );

var x;
var i;

for ( i = 0; i < 100; i++ ) {
    x = randu() * 10.0;
    console.log( 'j1(%d) = %d', x, j1( x ) );
}
