    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

    Installation

    npm install @stdlib/math-base-special-besselj1

    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 ) );
    }
