The choice whether a program exist in Octave is based only on comparing package/octave documentation with the TISEAN documentation. As of now I have not compared any code, nor checked if any sample data gives the same results from both functions (the octave ones and the TISEAN ones). | The choice whether a program exist in Octave is based only on comparing package/octave documentation with the TISEAN documentation.
