j0

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

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

Bessel function of the first kind of order zero

Usage

var j0 = require( '@stdlib/math/base/special/besselj0' );

j0( x )

Compute the Bessel function of the first kind of order zero at x.

var v = j0( 0.0 );
// returns 1.0

v = j0( 1.0 );
// returns ~0.765

v = j0( Infinity );
// returns 0.0

v = j0( -Infinity );
// returns 0.0

v = j0( NaN );
// returns NaN

Examples

var randu = require( '@stdlib/random/base/randu' );
var j0 = require( '@stdlib/math/base/special/besselj0' );

var x;
var i;

for ( i = 0; i < 100; i++ ) {
    x = randu() * 10.0;
    console.log( 'j0(%d) = %d', x, j0( x ) );
}
