Export assignment j0

• j0(x: number): number

• Computes the Bessel function of the first kind of order zero.

  Parameters

  • x: number

    input value

  Returns number

  evaluated Bessel function

  Example

  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
