As of version 1.02 SegyMAT is intended to work with Octave version >2.1.64
If you have an older octave version installed you may need to :
- change line (app 399) in ReadSegy from : if (outtrace==1), to : if (outtrace==-1),
- 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.
