I have 2 arrays, one with distances and one with heigth.
heigth = [10 20 30 40]
distance = [1 2 3 4]
I want to be able to get the heigth at any given value from 1 to 4. The main idea is to be able to do:
getHeigth(1.5) --> 15

interp1(height,distance,heightinput)

The solution is correct although I asked for interpolating heigth when introducing the distance. It's just need to swap the arguments.

c= fit([1; 2; 3 ;4],[10 ;20; 30; 40],'poly2')

Later u can call c(1.5) results in 15
