24 total contributions since 2009

I started using Matlab in 1991 (v3.0). I propose generic or dedicated functions written in a pure Matlab style, always vectorized with sound documentation.
My professional Interests: geophysics, volcanology, seismology, modelling, signal processing, ground deformation, mapping, graphics.
