Struct TruncatedEig

pub struct TruncatedEig<A: Scalar> {
    pub constraints: Option<Array2<A>>,
    /* private fields */
}

Truncated eigenproblem solver

This struct wraps the LOBPCG algorithm and provides convenient builder-pattern access to parameter like maximal iteration, precision and constraint matrix. Furthermore it allows conversion into a iterative solver where each iteration step yields a new eigenvalue/vector pair.

Fields

constraints: Option<Array2<A>>
