First to use seismic waves to determine the near-surface medium structure, play an important role in the exploration and development of mineral resources in construction. Seismic ray tracing method is an effective tool to study seismic wave propagation, currently used methods are finite difference equation method and the minimum path method. The shortest path method originated in network theory, for the first time by the Nakanishi and Yamaguchi applied to the seismic ray trail. Moser and Klimes and Kvasnicha shortest path method were studied in detail. Through continuous research scientific and technical personnel, the shortest path method has been developed more mature, the basic arithmetic calculation procedure is relatively fixed. It is called fourth-generation computer language MATLAB language, the use of its rich resources function frees the programmer the tedious code. MATLAB language with a more intuitive, consistent with the code of the habit of thinking people, to provide use
