no use of if, for, or any kind of loop!

4. Write a MATLAB function called myfun.m that has two inputs, x (vec- tor) and a (scalar), and one output, y (vector). The output y should be the same size as x and defined as r(n) >a y(n) 0, r(n) = a -1, r(n)> >> myfun ( [0.2 0.9 0.6 -0.1 1.2], 0.6) ans = -1 1 0 -1 1 Your program should not use any for or while loops and it should not use any if statements. Your program need not do any error checking. For full credit, write the correct syntax for a MATLAB function (the full contents of the .m file)
