## Minimize function with L-BFGS-B algorithm

Hi Team,
can you please help me the right function to implement minimize function with L-BFGS-B algorithm. Also, below are the boundaries I want to pass to the function.
a0= (0,15)
a1=(-15,30)
a2=(-30,30)
a3=(-30,30)
a4=(0,2.5)
a5=(2.5,5.5)
bnds=(a0,a1,a2,a3,a4,a5)
I'm looking for an equivalent function to implement below solver which was coded in python.
sol= minimize(objective,β4, method='L-BFGS-B', bounds=bnds).
Regards,

Team? What team? Ain't no team here. Perhaps you misunderstand what Answers is, as an open forum visited by volunteers.
The bound constrained minimizer you will find in MATLAB (the optimization toolbox) is FMINCON, which does not have that specific algorithm coded as an optiion as I recall. But FMINCON should be eminently suitable as a replacement.
Or you can use tools in the global optimization toolbox, like GA. GA is not in that general class of solver though.
Finally, you can look on the File Exchange, where you might find something closer to your target algorithm. Or, you might not.
