BESSELI
Calculates the modified Bessel function of the first kind.
Syntax:
BESSELI(x; n)
- returns the modified Bessel function of the first kind, of order n, evaluated at x.
- The modified Bessel function of the first kind In(x) = i-nJn(ix), where Jn is the Bessel function of the first kind.
Example:
BESSELI(1; 1)
- returns 0.565159103992.
