[julia-users] Passing parameters to 'optimize'

[Mathieu Taschereau-Dumouchel]

I am trying to optimize a simple function that takes a parameter as an 
argument. Something like:

a=2
f(x)=-(x-a)^2
optimize(f)

Is there any way to do this? I have played quite a bit with optimize 
without success.

Thanks a lot
Mathieu
