LU factorization result for general square matrices

Stores the original square matrix for use with LAPACK's DGESV routine. Unlike amChol, which caches the explicit triangular factor, amLU retains A and delegates factorization to base::solve at solve time.

Slots

A

Numeric square matrix; the original matrix passed to lu_factor.

source_id

Character string; the object_id of the source adgeMatrix, or NA for base matrices.

precision

Character string; "strict" or "fast", or NA for base matrices.

backend

Character string; the preferred backend of the source object, or NA for base matrices.
