Detailed Documentation
This MATLAB program implements the complete Empirical Mode Decomposition (EMD) algorithm. The implementation includes the core EMD decomposition process with proper handling of sifting operations, envelope construction using cubic spline interpolation, and intrinsic mode function (IMF) extraction criteria. The code features adaptive stopping conditions for the sifting process and efficient residue management. A simple demonstration example is provided to showcase the decomposition of sample signals into their IMF components, illustrating the step-by-step decomposition process and resulting signal analysis capabilities. The implementation maintains mathematical accuracy while ensuring computational efficiency through optimized array operations and boundary condition handling.
