Hybrid VDP-Duffing Nonlinear Dynamics Toolbox

Interactive MATLAB GUI for hybrid Van der Pol-Duffing simulation with Nth-order RC ladder support.

This toolbox provides an interactive MATLAB GUI for simulating and visualizing hybrid Van der Pol-Duffing nonlinear dynamics using a Simscape RC circuit realization.

The toolbox supports Simulink-only simulation, Nth-order RC ladder modeling, selectable raw and bandwidth-compensated math modes, and multiple nonlinear-dynamics visualization tools including phase portrait, state-vs-excitation, power spectrum, Poincare section, spectrogram, and return map.

Version 2.0.1 includes corrected N=2 RC ladder behavior, improved package metadata for MATLAB File Exchange, and a File Exchange-safe upload package without p-code.

Arduino Due support is included for hardware-oriented waveform deployment workflows, but Arduino hardware is required only for deployment mode. Simulink-only simulation works without Arduino hardware.
