Evolution of the vector of residual correlations b with the iterations of the LARS/homotopy. The scenario is composed by four sources located at θ= [-36°, -30°, 30°, 50°], M = 10 sensors, N = 600 snapshots, SNR = 0dB. The final solution is achieved after 16 iterations of the LARS/homotopy and it is chosen as the first one that lies within the K-S limits of the 99%. Note that the residual correlation is almost flat.
