Let S(x) be a quadratic spline that interpolates Matlab programming. Let S(x) be a quadratic spline that interpolates on the on the interval at 41 equally spaced nodes in the interval [-1,1]. Evaluate f(x)-S(x) at 200 equally spaced x values with x₁ = -1 and x₂₀₀ = 1 and plot the error f(x) - p(x). What are the maximum positive error? What are the maximun negative error?
