You can use polyfit or the packages [https://octave.sourceforge.io/signal/ signal] or [https://octave.sourceforge.io/optim/ optim] to achieve these task but these are not graphical tools. | You can use polyfit or the packages [https://octave.sourceforge.io/signal/ signal] or [https://octave.sourceforge.io/optim/ optim] to achieve these task but these are not graphical tools. | ||
A tool moving closer to the curve fitting toolbox is available for linear regression [https://andreasstahel.github.io/Octave/FitTool.m FitTool.m] and for nonlinear regression [https://andreasstahel.github.io/Octave/FitToolNL.m FitToolNL.m].

== How to Programmatically Identify If You're Running Octave == | |||
Because you may want to write cross-platform compatible code but make use of Octave-specific features when they're available, it may be necessary to programmatically detect the program environment. The following function can be used to detect whether it is being run in Octave. Due to the persistent variable it can be called repeatedly without a heavy performance hit. | |||
%% Return: true if the environment is Octave. | |||
%% | |||
function retval = isOctave | |||
persistent cacheval; % speeds up repeated calls | |||
if isempty (cacheval) | |||
cacheval = (exist ("OCTAVE_VERSION", "builtin") > 0); | |||
end | |||
retval = cacheval; | |||
end | |||
