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