Initialize two row vectors a and b of arbitrary but equal lengths (pick any length 3) with random numbers between 0 and 1. Recalling that the dot product between two vectors is = ||||cos, calculate the angle, , between the two vectors (radians or degrees is fine just state what you used). Note: You can use built-in inverse trigonometric functions from Matlab You may not use the built-in dot and norm functions from Matlab You should not write products like a(1)*b(1)+a(2)*b(2)+, etc.

USE MATLAB SOFTWARE !!!!
