A MATLAB program for comprehensive heart rate variability analysis featuring both linear methods (spectral distribution and statistical descriptors) and nonlinear approaches (sample entropy and wavelet analysis) with detailed reporting and visualization capabilities.

Detailed Documentation

This MATLAB-based heart rate variability analysis toolbox implements both linear and nonlinear analysis techniques with comprehensive reporting and visualization features. The linear analysis module includes spectral distribution analysis using FFT-based algorithms for frequency domain evaluation and statistical descriptors (mean, SDNN, RMSSD) for time-domain characterization. Nonlinear analysis components feature sample entropy calculation for signal complexity assessment and wavelet transform implementation for multi-resolution time-frequency analysis. The program generates detailed reports with graphical outputs including power spectrum plots, entropy comparisons, and wavelet scalograms, providing researchers with a complete toolkit for investigating HRV characteristics and trends through multiple analytical perspectives.
