USING MATLAB

Good evening can you help me with this exercise that is programming in matlab thank you very much. The first and second exercises are separate and the fourth exercise is using 1 and 2.

1. Program a mneville function, which receives a data table of n nodes and calculate the coefficients of the interpolating polynomial in Newton's form using the Neville method. The declaration of the function will be as follows: % Description % x the abscissa vector of the nodes as row % and the ordinate vector of the nodes as row % c the diagonal of the matrix of differences divided with the polynomial coefficients in Newton's form function c = mneville (x, y) Test your function with the data table: xy 1.
