Hi,

I am kind of struggling with scattered interpolation in Julia for 2D. What I have is a bunch of points (x,y,w), where x and y are coordinates and w is the value. I want to interpolate onto a regular grid. Currently for me this can be achieved by calling Python using linear interpolation:

```
using PyPlot
n = 100
X, Y, W = rand(n), rand(n), rand(n)
interval = 0.02
xi = range(minimum(X), stop=maximum(X), step=interval)
yi = range(minimum(Y), stop=maximum(Y), step=interval)
# Perform linear interpolation of the data (x,y) on grid(xi,yi)
triang = matplotlib.tri.Triangulation(X,Y)
interpolator = matplotlib.tri.LinearTriInterpolator(triang, W)
Xi = [y for x in xi, y in yi]
Yi = [x for x in xi, y in yi]
wi = interpolator(Xi, Yi)
```

Similar things can be done in MATLAB with scatteredInterpolant method.

I tried to look at the interpolation packages in Julia, but nothing works so far. Is there a native Julia way of doing this?

Thanks!
