( 3 marks) Write the MATLAB commands that assign 3 and 4 to the variables foo and boo, respectively. Then, create a column vector W with the elements foo3boo!fooln(fooboo)3boofoo(foo+boo)2(boo)2 where y ! is the factorial of y, for which you should use a built-in MATLAB function, and ln(x) is the natural logarithm of x. Finally, compute and output the average of the elements in W
