Function rgsl::bessel::In_array

pub fn In_array(nmin: i32, nmax: i32, x: f64, result_array: &mut [f64]) -> Value

This routine computes the values of the regular modified cylindrical Bessel functions I_n(x) for n from nmin to nmax inclusive, storing the results in the array result_array. The start of the range nmin must be positive or zero. The values are computed using recurrence relations for efficiency, and therefore may differ slightly from the exact values.
