For the following set of data, write a MATLAB code to fit thecurve 
to the data. Your MATLAB code must use’polyfit’ command to find a and b, then plot the fitted curve inred color, also plot the data points in form of blue * (Asterisk).Name the x axis as ‘X values’ and y axis as ‘System Response’. Putyour code and the plot in an MS-Word or PDF file and upload here.To copy the figure to Word file, you can go to figure and choose”Edit” from the menu then choose
