A simple code for l1-l2 Deconvolution via IRLS

The function l1_l2_irls.m is used to solve the deconvolution problem with sparsity constraints on the reflectivity series. In other words, one seeks the sparse time series (series of reflection coefficients) that reproduces the seismogram when convolved with the source wavelet
