1. (25 pt) The variables x = 2, y = 4, and z = 8 are defined in the template m-file. Write one-line MATLAB commands that carry out the assignments listed below. Make sure to assign to the variable names listed below (e.g. E1, E2). (a) E1 104+7 (b) E2 In(z+2y) y- = (c) E3 standard deviation of x, y, and z. (d) E4 = a row vector of 100 linearly spaced numbers between x and z. [E1 E2 E3 E1 E2 E3 E1 E2 E3] (e) E5 (Note: you will get zero point for this 1 2 E3 E1 E2 E3 E1 E2 E3 question if you directly type in each element of E5 in your code)
