MATLAB Implementation of Stochastic Subspace Method

Main program code for stochastic subspace method in MATLAB, enabling high-precision signal identification. Developed based on "Dielectric Loss Angle Measurement Method Using Stochastic Subspace and Least Squares" and Dr. Chang Jun's dissertation "Application Research of Stochastic Subspace Method in Bridge Modal Parameter Identification". The implementation includes algorithms for system identification and modal analysis.
