Store a general square matrix for LU-based solving

Wraps a square numeric matrix or adgeMatrix in an amLU object. The actual LU decomposition is performed by base::solve at solve time via LAPACK's DGESV.

Usage

lu_factor(A)

Arguments

A

A square numeric matrix or adgeMatrix.

Value

An amLU object.

Examples

m <- matrix(c(2, 1, 5, 3), nrow = 2)
fac <- lu_factor(m)
fac
#> amLU [2x2 | NA | source: NA]
