  A new technique for approximating the entire solution set for a nonlinear
system of relations (nonlinear equations, inequalities, etc. involving
algebraic, smooth, or even continuous functions) is presented. The technique is
to first plot each function as a pixel matrix, and to then perform a sequence
of basic matrix operations, as dictated by how variables are shared by the
relations in the system. The result is a pixel matrix graphing the approximated
simultaneous solution set for the system.
