MATLAB Time-Frequency Analysis Toolbox Source Code Implementation

The Time-Frequency Analysis Toolbox represents a powerful MATLAB source code implementation designed to enhance MATLAB's native time-frequency analysis functionality. This toolbox incorporates diverse computational tools that enable users to perform advanced signal analysis through specialized algorithms including Short-Time Fourier Transform (STFT), Wavelet Transform, and Wigner-Ville Distribution implementations. The codebase features modular function design, allowing for in-depth signal characterization through customizable windowing functions, frequency resolution parameters, and time-resolution trade-off adjustments. Furthermore, the toolbox supports extensive customization options through configurable input parameters, enabling users to optimize analysis settings based on specific application requirements. Key functions include spectrogram computation with adaptive window sizing, cross-time-frequency analysis for multi-signal comparison, and signal feature extraction algorithms for pattern recognition. This implementation provides robust analytical capabilities for various application scenarios, offering reliable and precise time-frequency representations through well-structured MATLAB classes and functions that follow object-oriented programming principles for enhanced code maintainability and extensibility.
