SeismicLab is a MATLAB seismic data processing package. The package can
be used to process small seismic data sets and, it is mainly intended for
research and teaching purposes. Scripts to read
and write SU data (the SEGY flavor
used by Seismic Un*x) are provided. A particular feature of this
package is that the SEGY headers are loaded into a structure that can be
easily assessed by MATLAB.
