Please send me the MATLAB code for the given question. I will give you an example for the getting the exact idea.

Like you can see this question no. 5. And below is the snapshot of the MATLAB code for it.

Like this I want a working MATLAB code for question no. 10. Thanks

10 Project ai = (1,0) onto a2 (1,2). Then project the result back onto aj. Draw these projections and multiply the projection matrices P P2: Is this a projection? 5 5 Compute the projection matrices aaT/aTa onto the lines through aj = (-1,2,2) and a2 = (2,2, -1). Multiply those projection matrices and explain why their prod- uct PPis what it is. question_5.m function question_5(a1, a2) P1 = get_projection_matrix(al); P2 = get_projection_matrix(a2); disp("P1 is"); disp(P1); disp("P2 is"); disp(P2); disp("P1 * P2 is") disp(P1*P2) end 10 Project ai = (1,0) onto a2 (1,2).
