Seismic ray tracing code

WebThe concept of a ray is very useful. It is a line drawn in space that corresponds to the direction of the flow of radiant energy. Rays are a geometric idealization; they have no width. As such, a ray is a mathematical device rather than a physical entity. In practice, we can produce very narrow beams or pencils (as, for example, a laser beam ... WebProject SEIZMO is a Matlab and GNU Octave based toolbox encompassing a collection of over 700 functions that provide a framework for seismic data preparation, quality control, and analysis akin to that of Seismic Analysis Code with a focus on passive source …
