Gerschgorin Disk Estimator (GDE) for Source Number Detection in Uniform Linear Arrays (ULA) with SNR Performance Analysis

This program implements the Gerschgorin Disk Estimator (GDE) method to evaluate source number detection performance in Uniform Linear Arrays (ULA) across varying SNR levels using Monte-Carlo simulations. The implementation involves covariance matrix computation, eigenvalue decomposition, and GDE thresholding for statistical performance analysis.
