"UMFPACK /\u02C8\u028Cmfp\u00E6k/ is a set of routines for solving sparse linear systems of the form Ax=b, using the Unsymmetric MultiFrontal method (Matrix A is not required to be symmetric). Written in ANSI/ISO C and interfaces with MATLAB (Version 6.0 and later) SciPy, and thus SciPy-relied software FuncDesigner, Sage, PythonXYIt appears as a built-in routine (for lu, backslash, and forward slash) in MATLAB, and includes a MATLAB interface, a C-callable interface, and a Fortran-callable interface."@en .
