compute_u: bool,
compute_v: bool,
eps: <N as ComplexField>::RealField,
max_niter: usize
) -> Option<SVD<N, R, C>>
Attempts to compute the Singular Value Decomposition of matrix
using implicit shift.
Arguments
compute_u
− set this totrue
to enable the computation of left-singular vectors.compute_v
− set this totrue
to enable the computation of right-singular vectors.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.
pub fn rank(&self, eps: <N as ComplexField>::RealField) -> usize
[src]
Computes the rank of the decomposed matrix, i.e., the number of singular values greater
than eps
.
pub fn recompose(
self
) -> Result<Matrix<N, R, C, <DefaultAllocator as Allocator<N, R, C>>::Buffer>, &'static str>
[src]
self
) -> Result<Matrix<N, R, C, <DefaultAllocator as Allocator<N, R, C>>::Buffer>, &'static str>
Rebuild the original matrix.
This is useful if some of the singular values have been manually modified.
Returns Err
if the right- and left- singular vectors have not been
computed at construction-time.

) -> Result<Matrix<N, C, R, <DefaultAllocator as Allocator<N, C, R>>::Buffer>, &'static str> where
DefaultAllocator: Allocator<N, C, R>,
Computes the pseudo-inverse of the decomposed matrix.
Any singular value smaller than eps
is assumed to be zero.
Returns Err
if the right- and left- singular vectors have not
been computed at construction-time.

DefaultAllocator: Allocator<N, C, C2>,
DefaultAllocator: Allocator<N, <R as DimMin<C>>::Output, C2>,
ShapeConstraint: SameNumberOfRows<R, R2>,
Solves the system self * x = b
where self
is the decomposed matrix and x
the unknown.
Any singular value smaller than eps
is assumed to be zero.
Returns Err
if the singular vectors U
and V
have not been computed.
