Mass-Dampening-Stiffness Matrix EOM

Program sets up Mass-Dampening-Stiffness Matrices for proprtionally damped system of mass, springs

Program will take a description of a system containing masses and springs with proportional dampening and will output the mass[M], dampening[D] and stiffness[K] matrices for that system with respects to its system of equations as shown below.

M*d2x/dt^2+D*dx/dt+K*x=F

Program can handle both numeric and symbolic equations.
