Variable elimination (Gaussian elimination, Fourier-Motzkin elimination),
Moore-Penrose pseudoinverse, reduction to reduced row echelon form, value substitution,
projecting a vector on the convex polytope described by a system of (in)equations,
simplify systems by removing spurious columns and rows and collapse implied equalities,
test if a matrix is totally unimodular, compute variable ranges implied by linear
(in)equalities.
