Methods seem to match but don't

I’m trying to call a function I’ve defined with only on method but will not call although I’m pretty sure all of my types are matching up

a=[1,2,3]
b=[3,2,1]
function foo(a::Array{Float64,1}, b::Array{Float64,1}, c)
   #definition
end
foo(a,b,0.1)

The first two arguments match but not the last one.

They are arrays of Ints. Define your method as

function foo(a::AbstractVector, b::AbstractVector, c)
   #definition
end

or just

function foo(a, b, c)
   #definition
end

You won’t lose any performance and things will just work.

Or use a parametric method

a=[1,2,3]
b=[3,2,1]
function foo(a::Array{T,1}, b::Array{T,1}, c) where {T}
   #definition
end
foo(a,b,0.1)
