y0
Compute the Bessel function of the second kind of order zero.
The Bessel function of the second kind of order zero is defined as
Usage
var y0 = require( '@stdlib/math/base/special/bessely0' );
y0( x )
Computes the Bessel function of the second kind of order zero at x
.
var v = y0( 0.0 );
// returns -Infinity
v = y0( 1.0 );
// returns ~0.088
v = y0( Infinity );
// returns 0.0
If x < 0
or x
is NaN
, the function returns NaN
.
var v = y0( -1.0 );
// returns NaN
v = y0( -Infinity );
// returns NaN
v = y0( NaN );
// returns NaN
Examples
var randu = require( '@stdlib/random/base/randu' );
var y0 = require( '@stdlib/math/base/special/bessely0' );
var x;
var i;
for ( i = 0; i < 100; i++ ) {
x = randu() * 10.0;
console.log( 'y0(%d) = %d', x, y0( x ) );
