How do I maximize a function ?

[Pranav Bhat]

How do I obtain the maximum value of a function over an interval?

In R I would do something like:

f <- function(x) { x ^ 2}

optimize(f, c(0, 100), maximum=TRUE)

Pkg.add("Optim")

using Optim

and follow this section of the docs: http://www.juliaopt.org/Optim.jl/stable/user/minimization/#minimizing-a-univariate-function
