Struct DiffOpts 

pub struct DiffOpts {
    pub method: Symbol,
    pub h: f64,
}

Options controlling a numeric-differentiation call.

method = auto first uses a symbolic CAS body when the function has one, then a registered differentiator named by the function’s differentiator_hint, then central finite difference.

Fields

method: Symbol

The differentiator method to use, or auto to follow the automatic symbolic, hinted-exact, then finite-difference order.

h: f64

The finite-difference step size.

Implementations

impl DiffOpts

pub fn auto() -> Self

Returns default options: the auto method with a small default step.

Examples

use sim_lib_numbers_numeric::DiffOpts;

let opts = DiffOpts::auto();
assert_eq!(opts.method.to_string(), "auto");
assert!(opts.h > 0.0);
