SegyMAT folder must be in your the Matlab (or Octave) search path.  
Some knowledge of how it works the  "Matlab Search Path"  is necessary.
Is recomended to put the program in  "work"  folder and Segymat in another folder. Put "work" on the top of the search folder and Segymat as second option.
If you have compatibility problems with "Robust toolbox" remove it this toolbox of your search path.
