Python-exposed structure to marshall complex multi-determinant information between Rust and Python.

Implementations

impl PyMultiDeterminantsComplex

pub fn new( basis: Vec<PySlaterDeterminantComplex>, coefficients: Bound<'_, PyArray2<Complex<f64>>>, energies: Bound<'_, PyArray1<Complex<f64>>>, density_matrices: Option<Vec<Bound<'_, PyArray2<Complex<f64>>>>>, threshold: f64, ) -> Self

Constructs a set of complex Python-exposed multi-determinants.

Arguments

• basis - The basis of Slater determinants in which the multi-determinantal states are expressed.

• energies - The energies of the multi-determinantal states.
• density_matrices - The optional density matrices of the multi-determinantal states.
• threshold - The threshold for comparisons.
