w_jn.c 23 * For n=0, ieee_j0(x) is called,
26 * from values of ieee_j0(x) and ieee_j1(x).
e_j0.c 16 * Method -- ieee_j0(x):
17 * 1. For tiny x, we use ieee_j0(x) = 1 - x^2/4 + x^4/64 - ...
18 * 2. Reduce x to |x| since ieee_j0(x)=ieee_j0(-x), and
42 * y0(x) = 2/pi*(ieee_j0(x)*(ln(x/2)+Euler) + x^2/4 - ...)
43 * therefore ieee_y0(x)-2/pi*ieee_j0(x)*ln(x) is an even function.
45 * y0(x) = U(z)/V(z) + (2/pi)*(ieee_j0(x)*ln(x)), z= x^2
50 * Note: For tiny x, U/V = u0 and ieee_j0(x)~1, hence
113 * ieee_j0(x) = 1/ieee_sqrt(pi) * (P(0,x)*cc - Q(0,x)*ss) / ieee_sqrt(x)
191 * ieee_j0(x) = 1/ieee_sqrt(pi) * (P(0,x)*cc - Q(0,x)*ss) / ieee_sqrt(x
