Matlab

Develop a program that gets data again from the mat file and then Plots the individual points with 'o' circle marks Fits a cubic spline to the data, use "star" marks Fits a linear least square curve, use "diamond" marks Fits a 7th order polynomial, use "x" marks Plot all curves simultaneously using different symbols for the plots. Be sure to axis to expand the range for better visibility of the final graph. See also help plot Do this in an m-file and attach the final graph. Answer this question. Which curve fits the data the best and why
