profil.m

具有特色的地震数据处理源码

function profil(datain)
%profil(datain)
%
%This module displays information about a data variable
%that has been set up in the official DSI data format.
%-similar to 'profile' in Insight
%
%INPUT
%datain - data in DSI format
%
%DSI customized VSP processing software
%written by Gervais Perron
