Dear Andrew, Nope, unfortunately it's not what I am trying to achieve. The code you've kindly (let's forget the interpolation task, what I really meant is some programming construct, so it's OK with no delta_x) submitted gives:
my_interp = make_interp(x, y) println(my_interp(2.1)) # prints 4.5 y[2] = 5 println(my_interp(2.1)) # prints 5.4 and I also would like to get 4.5 in the second case. All the best, Marek
