An interface for solving systems of Hermitian (or real symmetric) linear equations.

If you plan to solve many equations with the same Hermitian (or real symmetric) coefficient matrix A but different b vectors, it’s faster to factor the A matrix once using the FactorizeH trait, and then solve using the BKFactorized struct.

Required Methods

fn solveh_inplace<'a, S: DataMut<Elem = A>>(
    &self,
    b: &'a mut ArrayBase<S, Ix1>
) -> Result<&'a mut ArrayBase<S, Ix1>>

Solves a system of linear equations A * x = b with Hermitian (or real symmetric) matrix A, where A is self, b is the argument, and x is the successful result. The value of x is also assigned to the argument.

Panics

Panics if the length of b is not the equal to the number of columns of A.

Provided Methods

fn solveh<S: Data<Elem = A>>(&self, b: &ArrayBase<S, Ix1>) -> Result<Array1<A>>

Solves a system of linear equations A * x = b with Hermitian (or real symmetric) matrix A, where A is self, b is the argument, and x is the successful result.

Panics

Panics if the length of b is not the equal to the number of columns of A.

fn solveh_into<S: DataMut<Elem = A>>(
    &self,
    b: ArrayBase<S, Ix1>
) -> Result<ArrayBase<S, Ix1>>

Solves a system of linear equations A * x = b with Hermitian (or real symmetric) matrix A, where A is self, b is the argument, and x is the successful result.

Panics

Panics if the length of b is not the equal to the number of columns of A.
