说明： 标准SEG-Y格式地震数据读写程序，不需要检查道头字，程序会自动读取争取的线号、道号、XY坐标以及样点双程旅行时序列，在自己编写的处理程序中可以直接引用。
(Seismic data in SEG-Y formate read/write)

As of version 1.02 SegyMAT is intended to work with Octave version >2.1.***
If you have an older octave version installed you may need to :
1) change line (app 399) in ReadSegy
from : if (outtrace==1),
to : if (outtrace==-1),
2) comment line (app 214) in ReadSegyFast :
from : Data=ibm2num(uint32(Data));
to : % Data=ibm2num(uint32(Data));
These two changes have been successfully applied to octave version 2.1.57.
_____________________________________
* A note on speed
SegyMAT in Octave runs MUCH slower (about a factor 5) than in Matlab when reading in SEG-Y header values. If you just need to read the trace data try using :
data=ReadSegy(filename), which makes use of ReadSegyFast.
In any case (Matlab or octave) this is much faster, and specifically, Matlab and Octave performs equally well.
