pub fn chebyshev_second<N: ComplexField + FromPrimitive + Copy>(
n: u32,
tol: N::RealField,
) -> Result<Polynomial<N>, String>Expand description
Get the nth chebyshev polynomial of the second kind.
Gets the nth chebyshev polynomial of the second kind over a specified field. This is done using the recursive formula and is properly normalized.
§Errors
Returns an error on invalid tolerance
§Panics
Panics if a u8 can not be transformed into the generic type.
§Examples
use bacon_sci::special::chebyshev_second;
fn example() {
let u_3 = chebyshev_second::<f64>(3, 1e-8).unwrap();
assert_eq!(u_3.order(), 3);
assert!(u_3.get_coefficient(0).abs() < 0.00001);
assert!((u_3.get_coefficient(1) + 4.0).abs() < 0.00001);
assert!(u_3.get_coefficient(2).abs() < 0.00001);
assert!((u_3.get_coefficient(3) - 8.0).abs() < 0.00001);
