What you want to do really is passing an instance of a data structure (composite data type) to your function. to do this, first design your data type:

type MyType
  x::Vector
  a
  b
  c
end

and implement dxtd function:

function dxdt(val::MyType)
  return val.a*val.x^2 + val.b*val.x + val.c
end

then some where in your code you make an instance of MyType like this:

myinstance = MyType([],0.0,0.0,0.0)

you can update myinstance

myinstance.x = [1.0,2.8,9.0]
myinstance.a = 5

and at the end when myinstance get ready for dxxt

dxdt(myinstance)
