Struct ConnectionFormula 

pub struct ConnectionFormula {
    pub from_basis: String,
    pub to_basis: String,
    pub matrix: Vec<Vec<Complex<f64>>>,
    pub valid_range: Option<(f64, f64)>,
}

A connection formula: expresses basis A in terms of basis B.

If b = (b_1, ..., b_n)^T are the coefficients in basis B and a = (a_1, ..., a_n)^T in basis A, then a = matrix * b.

Fields

from_basis: String

Human-readable label for the source basis.

to_basis: String

Human-readable label for the target basis.

matrix: Vec<Vec<Complex<f64>>>

Connection matrix stored in row-major order.

valid_range: Option<(f64, f64)>

Parameter interval (lo, hi) for which the formula is valid.

Implementations

impl ConnectionFormula

pub fn apply( &self, basis_b_coeffs: &[Complex<f64>], ) -> Result<Vec<Complex<f64>>, ConnectionError>

Apply the connection formula: compute a = matrix * b.

Returns an error when basis_b_coeffs has a different length than the number of columns in matrix.

pub fn is_valid_at(&self, param: f64) -> bool

Check whether a given parameter value falls within the valid range.

pub fn rows(&self) -> usize

Return the number of rows (output dimension) of the matrix.

pub fn cols(&self) -> usize

Return the number of columns (input dimension) of the matrix.

Trait Implementations

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

Performs copy-assignment from source.

impl Debug for ConnectionFormula

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

Formats the value using the given formatter.
