# Dynamical Systems Analysis

## Overview

Qualitative and quantitative analysis of nonlinear dynamical systems. Phase portraits, fixed point classification, stability analysis, bifurcation diagrams, Poincare sections, and Lyapunov exponent computation.

## When to Use

- Visualizing flow in phase space (2D and 3D systems)
- Finding and classifying fixed points (stable/unstable nodes, spirals, saddles, centers)
- Bifurcation analysis (how qualitative behavior changes with parameters)
- Detecting chaos (Lyapunov exponents, sensitivity to initial conditions)
- Poincare sections for periodicity analysis
- Limit cycle detection and characterization
