Derivatives of Polynomials My Solutions Implement a function base on the complete Horner's method that returns the kth derivative of a polynomial evaluated at a given position p[k](z0) Your function should accept the following inputs: a - vector containing the coefficients of the polynmial of degree n, of size 1 by ( n+1), where the coefficients of the polynomial are listed from lowest order to highest order. For example, p(z)=1/2+z+2z2+3z3 is represented by a=[1/2,1,2,3] z0 - where the appropriate derivative will be computed. k - the order of the derivative to compute, where k bigger than or equal to 0 . (The Oth derivative is just the function itself) Your function should return the following output: w - The value of the k th derivative at z0. Function 0 Code to call your function ? \begin{tabular}{l|l} 1 & a=[25741]; \\ 2 & z=3; \\ 3 & k=4; \\ 4 & w= poly_diff(a,z0, k); \end{tabular}
