Lagrange_Interp(X,Y​,x)

Program to calculate Lagrange polynomial and the interpolated value

This program calculates the Lagrange coefficients and the interpolated value. The coefficients are displayed starting from the highest power. For eg: if there are 3 co-ordinates we expect a polynomial of order 2. In this case the first coefficient in the coefficient vector is that for x^2, then for x^1, and then for x^0.
