Struct sprs_ldl::LdlSymbolic [−][src]
Structure to compute and hold a symbolic LDLT decomposition
Implementations
impl<I: SpIndex> LdlSymbolic<I>[src]
pub fn new<N>(mat: CsMatViewI<'_, N, I>) -> Self where
N: Copy + PartialEq, [src]
N: Copy + PartialEq,
pub fn new_perm<N>(
mat: CsMatViewI<'_, N, I>,
perm: PermOwnedI<I>,
check_symmetry: SymmetryCheck
) -> Self where
N: Copy + PartialEq,
I: SpIndex, [src]
mat: CsMatViewI<'_, N, I>,
perm: PermOwnedI<I>,
check_symmetry: SymmetryCheck
) -> Self where
N: Copy + PartialEq,
I: SpIndex,
Compute the symbolic decomposition L D L^T = P A P^T where P is a permutation matrix.
Using a good permutation matrix can reduce the non-zero count in L, thus making the decomposition and the solves faster.
Panics
- if mat is not symmetric
pub fn problem_size(&self) -> usize[src]
The size of the linear system associated with this decomposition
pub fn nnz(&self) -> usize[src]
The number of non-zero entries in L
pub fn factor<N>(
self,
mat: CsMatViewI<'_, N, I>
) -> Result<LdlNumeric<N, I>, LinalgError> where
N: Copy + Num + PartialOrd, [src]
self,
mat: CsMatViewI<'_, N, I>
) -> Result<LdlNumeric<N, I>, LinalgError> where
N: Copy + Num + PartialOrd,
Compute the numerical decomposition of the given matrix.
