#### Bessel_i

Function: bessel_i (<v>, <z>) The modified Bessel function of the first kind of order v and argument z.

`bessel_i` is defined as inf ==== - v - 2 k v + 2 k \ 2 z > ------------------- / k! gamma(v + k + 1) ==== k = 0

although the infinite series is not used for computations.

There are also some inexact matches for `bessel_i`. Try `?? bessel_i` to see them.

```(%o1)                                true
(%i2) ```
