Question 1 Create a matrix 4x4 of integer random numbers between 10 and 60 a. Generate a (2x3) matrix of the original b. Generate a (4x3) matrix of the original with the row order reversed Replace the second column of the matrix with [1; -3 ; 5:7] Question 2 Write a MATLAB script to find a solution to the following set of linear equations: 4x1 + 6x2 + 2x3 - 2 4x1 + 9x3 = 4 3x + 4x + 2x2 - 6 Question 3 Evaluate the following expressions in MATLAB, where t=3si = V-1 and w-150x rad's. How do the answers compare? ae-20 = cos(wt) b. e-2 [cos(wt) + sin(w!)] c. el-21+lwe
