Bessel Functions: _j0, _j1, _jn

Compute the Bessel function.

double _j0( 
   double x 
);
double _j1( 
   double x 
);
double _jn( 
   int n,
   double x 
);

Parameters

• x
  Floating-point value.

• n
  Integer order of Bessel function.

Return Value

Each of these routines returns a Bessel function of x. You can modify error handling by using _matherr.

Remarks

The _j0, _j1, and _jn routines return Bessel functions of the first kind: orders 0, 1, and n, respectively.

Requirements
