Hello All,

looking into GNU Octave: Solvers

I see among other things:

Function File: [x, fvec, info, output, fjac] = fsolve (fcn, …

Pay special attention  to 'fvec' - I do not see it anywhere else in the webpage. OTOH later on I see:

On return, fval contains the value of the function fcn evaluated at x

I think that 'fval' and 'fvec' is the same and either one, but not both of the names should have been used. If I'm wrong, please explain the exact meaning of both items and difference between them.


You are correct. The documentation needs fixed.
Do you want to provide a fix?



"Do you want to provide a fix?" - here are the INSTRUCTIONS:

1) open the source code page from which the documentation is generated;
2) replace 'fvec' with 'fval' everywhere (you might need to learn how to use a text editor for that).
