DefaultAllocator: Allocator<<T as ComplexField>::RealField, <D as DimSub<Const<1_usize>>>::Output, Const<1_usize>>,
Computes the eigendecomposition of the given symmetric matrix with user-specified convergence parameters.
Only the lower-triangular part (including its diagonal) of m
is read.
Arguments
eps
− tolerance 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. Ifniter == 0
, then the algorithm continues indefinitely until convergence.

) -> Matrix<T, D, D, <DefaultAllocator as Allocator<T, D, D>>::Buffer>
[src]
&self
) -> Matrix<T, D, D, <DefaultAllocator as Allocator<T, D, D>>::Buffer>
Rebuild the original matrix.
This is useful if some of the eigenvalues have been manually modified.
