Struct ggez::graphics::na::RealSchur

pub struct RealSchur<N, D> where
    D: Dim,
    N: Real,
    DefaultAllocator: Allocator<N, D, D>,  { /* fields omitted */ }

Real Schur decomposition of a square matrix.

Methods

impl<N, D> RealSchur<N, D> where
    D: Dim + DimSub<U1>,
    N: Real,
    ShapeConstraint: DimEq<Dynamic, <D as DimSub<U1>>::Output>,
    DefaultAllocator: Allocator<N, D, <D as DimSub<U1>>::Output>,
    DefaultAllocator: Allocator<N, <D as DimSub<U1>>::Output, U1>,
    DefaultAllocator: Allocator<N, D, D>,
    DefaultAllocator: Allocator<N, D, U1>, 

fn new(
    m: Matrix<N, D, D, <DefaultAllocator as Allocator<N, D, D>>::Buffer>
) -> RealSchur<N, D>

Computes the Schur decomposition of a square matrix.

fn try_new(
    m: Matrix<N, D, D, <DefaultAllocator as Allocator<N, D, D>>::Buffer>,
    eps: N,
    max_niter: usize
) -> Option<RealSchur<N, D>>

Attempts to compute the Schur decomposition of a square matrix.

If only eigenvalues are needed, it is more efficient to call the matrix method .eigenvalues() instead.

Arguments

• eps − tolerence used to determine when a value converged to 0.
• max_niter − maximum total number of iterations performed by the algorithm. If this number of iteration is exceeded, None is returned. If niter == 0, then the algorithm continues indefinitely until convergence.

fn unpack(
    self
) -> (Matrix<N, D, D, <DefaultAllocator as Allocator<N, D, D>>::Buffer>, Matrix<N, D, D, <DefaultAllocator as Allocator<N, D, D>>::Buffer>)

Retrieves the unitary matrix Q and the upper-quasitriangular matrix T such that the decomposed matrix equals Q * T * Q.transpose().

fn eigenvalues(
    &self
) -> Option<Matrix<N, D, U1, <DefaultAllocator as Allocator<N, D, U1>>::Buffer>>

Computes the real eigenvalues of the decomposed matrix.

Return None if some eigenvalues are complex.

fn complex_eigenvalues(
    &self
) -> Matrix<Complex<N>, D, U1, <DefaultAllocator as Allocator<Complex<N>, D, U1>>::Buffer> where
    DefaultAllocator: Allocator<Complex<N>, D, U1>, 

Computes the complex eigenvalues of the decomposed matrix.
