The file size is 1.35 MB, Duffing Measure Model, non-linear Duffing equation solution solver. Duffing Measure model computes the solutions to the non-linear Duffing equation, which reads, x'' + 2 x' - x (1 - x2) = f cos( t), where each prime denotes a time derivative. The simulation displays the evolution of a group of oscillators with similar...
