Answer to Question #136295 in MatLAB for Rut Shah

Question

The gaussian function is de ned byf(x) =e^x^2:
(A) Write the barycentric form of the interpolating polynomialp3(x) for the gaussian function onthe interval [1;1] using four evenly spaced tting points.
(B) Use MATLAB to plot the gaussian function and thep3(x) you obtained in (A) on the sameaxes. Also plot the error on a separate graph.
(C) Use MATLAB to plot a tenth-order interpolating polynomialp10(x) using the barycentric formof the polynomial and eleven evenly spaced tting points on the same axis as the gaussian. Alsoplot the error on a separate graph.
(D) Compare and contrast the two interpolating polynomials
