Details:

Severity: Low/Minor

In the documentation (and help page) for sqp, the function prototype is 

[x, obj, info, iter, nf, lambda] = sqp (x0, phi)


Blindly copying that suggestion overloads the octave native function 'info()'


octave:1> info

octave:2> info = 2
info =  2
octave:3> info
info =  2
octave:4> 


Would suggest a different naming convention for the function (and any others
like it). It was quite a surprise to see optimization code start spewing
Octave information when I switched to nmsmax where I had previously used sqp.


Is there a warning variable that can be enabled to prevent accidental
overloads?

Thanks!
