Write a Matlab function p LagrangeInt(x,y) for polynomial interpolation using Lagrange form. The input for this function should be an array x with (n + 1) distinct points To, 21, t2,... , Zn and also an array of function values y, with (n +1) function values yo, y1, 32,.. . , Jn. Your function should return to a vector which contains the coefficients (in descend order) of your interpolation polynomial p such that p(x)-f( for i- 0,1,..., n.
