Right Preconditioning bug #81

Open

Using Gmres, the right preconditioning is not working properly. The error might be on line 948 of 'linsys.py'.

return self.x0 + self.linear_system.Mr * yk

Multiplying yk by the right preconditioner does not seem right. Instead, it should be an extra linear solve of the form

self.linear_system.Mr^(-1) * yk
