Higher-Order Spectral Analysis Toolbox for MATLAB

I would like to share my experience with the Higher-Order Spectral Analysis Toolbox for MATLAB. This toolbox proves exceptionally practical for analyzing and processing higher-order spectral data. The implementation includes functions for computing bispectrum, bicoherence, and trispectrum analysis using advanced algorithms like the direct FFT method and parametric approaches. Regardless of your research domain, this toolbox offers substantial utility through its comprehensive function library. You can effectively apply it to various fields such as acoustics research (using bispectral analysis for nonlinear system identification), signal processing (detecting phase-coupled components), seismology (analyzing non-Gaussian seismic signals), and biomedical engineering (characterizing EEG patterns). The toolbox features key functions like bispecd for direct bispectrum estimation and bicoher for computing bicoherence with proper statistical normalization. I hope this toolbox provides significant assistance in your research endeavors.
