*The following question requires to be answered through MATLAB*

Enter the following two vectors in Matlab:

satisfaction_class1 = [ 7 4 1 0.5 0.1 ]'; satisfaction_class2 = [ 6 3 1.2 0.5 0.2 ]';

These are fictitious values recording the average satisfaction levels of students in Class 1 and Class 2 (for the grades A-F respectively). Use this data to create the graph shown below. Paste the Matlab code (multiple lines are fine) that you used to recreate this figure. In the Matlab documentation for the bar command, you can find how to change the colors to the black/white scheme used below.
