5.9 y0(), y1(), yn(), Bessel functions of the second kind

These functions compute Bessel functions of the second kind.

y0 and y1 compute the functions of order 0 and 1 respectively. yn computes the function of order n.

double y0(double x);
double y1(double x);
double yn(int, double);

If x is positive and exceeds pi times 2^52, these functions return an ERANGE error, denoting total loss of significance in the result.

Note:

These functions are deprecated in ARM® Compiler 4.1 and later.
