Institut de Physique du Globe de Paris
I started using Matlab in 1991 (v3.0). I propose generic or dedicated functions always vectorized, toolbox-free, release-compatible, Octave-compatible and fully documented.
My professional Interests: geophysics, volcanology, seismology, modelling, signal processing, ground deformation, mapping, graphics.
