Introduction

SegyMAT is a set of Matlab files for reading and writing SEG-Y files from Matlab.

SegyMAT aims at being both simple to use to read SEG-Y files, and extensive enough to aid in writing complex seismic data.

A Python port of the library has initiated under the name : SegyPY

ADD : SegyMAT has a family member called lasYmat. A set of mfiles to read LAS files. It is currently under development, but useful.
