Module extendr_api::prelude::sparse::linalg::lu

Computes the LU decomposition of a given sparse matrix. See faer::linalg::lu for more info.

The entry point in this module is SymbolicLu and factorize_symbolic_lu.

Warning

The functions in this module accept unsorted input, and always produce unsorted decomposition factors.

Modules
