Hi there!

I have two Mathematica arrays: Xval and Yval.

Let's suppose a simple situation:

Xval[1]=1

Xval[2]=3

Xval[3]=5

Yval[1]=10

Yval[2]=20

Yval[3]=30

For a situation like this, where the arrays are small, I could do something like:

Func = Interpolation[{1,10},{3,20},{5,30}]

So there's no problem here. However, let's imagine that both Xval and Yval are arrays of length n which are read from a .txt file. I want to know if it is possible to interpolate Yval using Xval as the domain, without having to write explicitly the points [{1,10}...] by hand.

Cheers, M
