Problem 4: (7 Points) Explain what the following commands do. Command [1; -4; 7.1; 10; 2; 5; 8; 11] Description Creates a column vector of dimension 8 x= x(3:end) x(8: (-2):1) y = linspace(0,0.2, 4); A = rand (4,8) A 1:3, :) A(:) W = A*x y * w Multiplies 1x4 vector y with 4x1 vector w, resulting in a 1x1 vector (i.e. a number) reshape (x, 2,4) B = [eye (4), 2*ones (4) ] C = [A; B] D= C^(-1) E = c.^(-1)
