Function rgsl::bessel::In_scaled_array
[−]
[src]
pub fn In_scaled_array(
nmin: i32,
nmax: i32,
x: f64,
result_array: &mut [f64]
) -> Value
This routine computes the values of the scaled regular cylindrical Bessel functions \exp(-|x|) 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.
