*This function gives the value of the modified Bessel function.

*Bessel functions is also called cylinder functions because they appear in the solution to Laplace's equation in cylindrical coordinates.

*Bessel functions is also called cylinder functions because they appear in the solution to Laplace's equation in cylindrical coordinates.

*Bessel's Differential Equation is defined as: x^2 (d^2 y/dx^2) + x(dy/dx) + (x^2 - α^2)y =0

where α is the arbitary complex number.

where α is the arbitary complex number.

*But in most of the cases α is the non-negative real number.

*But in most of the cases α is the non-negative real number.

*The Bessel function of the 2nd kind of order  can be expressed as: Yn(x)=lt p tends to n {Jp(x)Cosp pi()- J-p(x)}/Sinp pi(), where Jn(x) is the Bessel functions of the first kind.
