fmincon - fminsearch : constrained simplex optimization in Octave?

[baptiste auguie]

Hello,


I'm porting a Matlab code to Octave. I used 'fmincon' function as a  
nonlinear fitting routine, allowing for constraints, and use of  
different optimization algorithms such as Gauss Newton, Simplex, ...

Is there a similar function in Octave?

Best regards,
