I have the data composing of 7 elements
x is from 0 → 3 incrementing by 0.5 y is from 1.8241 → -1.5427
I am supposed to use Lagrange's interpolation of three nearest neighbor data points.
I am supposed to write the code to do so in python but am struggling with setting up the equation.
I know l[0] = (x-x1/(x[0]-x[1])(x[0]-x[2])
But given the question that doesn't seem to be what I need and if so, using the 3 nearest neighbor data points do I still start at l[0].
Thanks for the help.
