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

Warning to all users and, in particular, to UofA geophysics students: Please, disclose the source of this material when using it for assignments and/or for your term projects. People got into trouble for using my codes and not telling the instructor that they were my codes. M D Sacchi, 9/2012
