Struct SmithCoefficients 

pub struct SmithCoefficients {
    pub a: f64,
    pub b: f64,
    pub c: f64,
    pub d: f64,
    pub e: f64,
}

Fully determined coefficients.

Fields

a: f64

Constant.

b: f64

Semicircular, sin(course).

c: f64

Semicircular, cos(course).

d: f64

Quadrantal, sin(2·course).

e: f64

Quadrantal, cos(2·course).

Implementations

impl SmithCoefficients

pub fn deviation_at(&self, course: CompassCourse) -> f64

Model deviation at a compass course, degrees.

Returns a plain f64, not a Deviation: a poorly conditioned fit may produce absurd values, and reporting them is more useful than refusing.

pub const fn as_input(&self) -> DeviationCoefficients

Converts to the partially specified form used by the interpolator.

Trait Implementations

impl Clone for SmithCoefficients

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl CompassModel for SmithCoefficients

Five-coefficient model as a CompassModel.

SmithCoefficients::deviation_at returns a plain f64 because a fit can produce absurd values; here a Deviation is required, so such values yield KernelError::OutOfRange.

fn deviation(&self, course: CompassCourse) -> Result<Deviation>

Deviation on course.

impl Copy for SmithCoefficients

impl Debug for SmithCoefficients

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for SmithCoefficients

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for SmithCoefficients

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
