Maxima Function
bessel_j (v, z)
The Bessel function of the first kind of order v and argument z.
bessel_j
computes the array besselarray
such that
besselarray [i] = bessel_j [i + v - int(v)] (z)
for i
from zero to int(v)
.
bessel_j
is defined as
inf ==== k - v - 2 k v + 2 k \ (- 1) 2 z > -------------------------- / k! gamma(v + k + 1) ==== k = 0
the infinite series is not used for computations.
