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 legend to understand the table is as follows:
 
 
{| class="wikitable"  
 
{| class="wikitable"  
|-style="background: LightGreen"
 
|Green means the function is ported, tested or is not needed
 
|-style="background: LightSalmon"
 
|Red means the function was thought to have been similar but isn't
 
|-style="background: Yellow"
 
|Yellow means that the correlation between the TISEAN and Octave function needs to be verified
 
 
|-
 
|-
|No color means that nothing about this function has been determined
