Have a look at Interpolations.jl. This example is equivalent to the interp2 function:

A = rand(8,20)
knots = ([x^2 for x = 1:8], [0.2y for y = 1:20])
itp = interpolate(knots, A, Gridded(Linear()))
itp(4,1.2)  # approximately A[2,6]

You might find the Dierckx.jl package helpful to achieve 2-d spline fitting. See for instance Spline2D.
