Question

Write a Matlab function of the form

psi = polyLagrange(k)


that takes as input the degree k of the shape functions desired and returns a structure psi of size 1 by k+1 with two fields, psi.fun and psi.der that store the polynomial coefficients,
in descending powers, of the k + 1 Lagrange shape functions and their derivatives, respectively. Use the Matlab function polyfit, as discussed in class, to generate the polynomials.
