simplicial factorization module
a simplicial factorization is one that processes the elements of the $QR$ factors of the input matrix by single elements, rather than by blocks. this is more efficient if the $QR$ factors are very sparse
Structs§
- Simplicial
QrRef - $QR$ factors containing both the symbolic and numeric representations
- Symbolic
Simplicial Qr - symbolic structure of the $QR$ decomposition
Functions§
- factorize_
simplicial_ numeric_ qr_ scratch - computes the size and alignment of the workspace required to compute the numerical $QR$ factorization of the matrix whose structure was used to produce the symbolic structure
- factorize_
simplicial_ numeric_ qr_ unsorted - computes the numerical $QR$ factorization of $A$.
- factorize_
simplicial_ symbolic_ qr - computes the symbolic $QR$ factorization of a matrix $A$, given the outputs of the pre-factorization steps
- factorize_
simplicial_ symbolic_ qr_ scratch - computes the size and alignment of the workspace required to compute the symbolic $QR$
