TAOLinearBoundSolver

class dolfin.cpp.la.TAOLinearBoundSolver(*args)

Bases: dolfin.cpp.common.Variable, dolfin.cpp.la.PETScObject

This class provides a bound constrained solver for a linear variational inequality defined by a matrix A and a vector b. It solves the problem:

Find \(x_l\leq x\leq x_u\) such that :math:`(Ax-b)cdot (y-x)geq 0,;

orall x_lleq yleq x_u`

It is a wrapper for the TAO bound constrained solver.
