Definition of a linear system

A linear system has the following components:

• A : coefficient matrix
• B : a matrix from which to build a preconditioner. Often this will just be A.
• rhs : the right hand side
• sol : a known solution, if any; there is a boolean to indicate
• init : a starting guess for iterative methods whether a solution is known.
• ctx : a void pointer for storing an arbitrary data item; this can be used by the user.
