Write a MATLAB function to implement the Hermite interpolation in Algorithm 3.3. Note that the index should run from 1 instead of 0 that is used in the textbook. This is because MATLAB does not allow index 0 Your function should use the same order of input below. Note that we do not return Q as in the algorithm. Instead, we calculate the interpolated function value at x. function y hermite (X,Y,YF,x) = X=number3 x 1 x 2 x n %-= value3 f(x 1) f(x 2) f(x n) x-interpolation, (x2) f"(x y nterpolated function value at x, i.e. H(x) x 2) .. x n) x = interpolation point X your implementation below end Save your function in 'hermite.n', and interpolate the tabular function given below at the point x 1.25. f(r) 110517 f (x) 0.22103 0.59673 147576 1.0 2.0 2.45960 Your function should return 1.1690.
