SU shell scripts to "merge" 4 figures into one and add labels

• Wiggles: Plot_4_w.sh was used to generate wiggles.pdf
• Images: Plot_4_i.sh was used to generate images.pdf
• First chmod a+x Plot_r_w.sh and then, chmod a+x Plot_r_i.sh
• psmerge should be the one in the SU distribution not the one in, for instance, /usr/texbin/psmerge

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

• Download test_l1_l2_irls.m (this program calls the function l1_l2_irls.m)
• Download l1_l2_irls.m
• Download wavelet w.mat and seismogram s.mat
• Results should look like: decon_irls.pdf
