cylBessel_i0 double cylBessel_i0(double x): Modified Bessel function of order zero
cylBessel_i1 double cylBessel_i1(double x): * Modified Bessel function of order one * * Returns modified Bessel function of order one of the * argument. * * The function is defined as i1(x) = -i j1( ix ). * * The range is partitioned into the two intervals [0,8] and * (8, infinity). Chebyshev polynomial expansions are employed * in each interval.
cylBessel_j0 real cylBessel_j0(real x): Bessel function of order zero
cylBessel_j1 real cylBessel_j1(real x): Bessel function of order one
cylBessel_jn real cylBessel_jn(int n, real x): Bessel function of integer order
cylBessel_y0 real cylBessel_y0(real x): Bessel function of the second kind, order zero Also known as the cylindrical Neumann function, order zero.
cylBessel_y1 real cylBessel_y1(real x): Bessel function of the second kind, order zero
cylBessel_yn real cylBessel_yn(int n, real x): Bessel function of second kind of integer order
