[julia-users] Re: Why do I get BoundsError() when trying to range an array with another array in a for loop?

[Ivar Nesje]

I'm not exactly sure what you are trying to do but maybe it is something 
like this:

x = [-1:1:2]
inter = polyal(Poly([1, -2, 1]), x)

for i in 1:length(x)
    if inter[i] == 0
        println("root in x=", x[i])
    end
end
