Question 1
Given A = [1, 2; 3, 4] and B = [4, 3; 2, 1], explain how you would compute the element-wise average of both matrices.
💡 Hint: Consider how you can build A and B into a single operation.
Question 2
Given a linear system represented by Ax = b where A is a random square matrix generated within MATLAB and b is a defined vector, solve for x and demonstrate using both inv(A) and backslash operator.
💡 Hint: Generate a random matrix and observe the output from both methods.
