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

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

    Bessel function of the second kind of order zero

    Installation

    npm install @stdlib/math-base-special-bessely0

    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 ) );
    }

    Notice

    This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
