Solving Polynomial Equations

Lagrange is a function that calculate equations of motion (Lagrange's equations) d/dt(dL/d(dq))- dL/dq=0. It Uses the Lagrangian that is a function that summarizes thedynamics of the system. Symbolic Math Toolbox is required.

solvesimul.m can be easily adapted to solve more equations but as it stands it will solve 2 unknowns in 2 equations (1 non-linear and one linear).To solve equations of this form... a*x + b*y = A (1) a1*x^2 + b1*y^2 = B (2)...with fsolve (used by solvesimul.m) you need to rewrite them so that they...

Graphical user interface (GUI) is used to solve up to two ordinary differential equations (ODEs). Results can be plotted easily. Choose between MATLAB's ode45 (non-stiff solver) or ode15s (stiffer solver).This is primarily a teaching tool.
