2) Assign A1 to [-2:1;1:-1:-2;-2:2:4), v1 to linspace(-2,4,4), and x to -2, and set A2 equal to a 3X3 matrix of all 5's. Compute the following variables first by hand (don't turn in), then confirm your result by computing in the script below. If any result is not defined by an operation, indicate by setting the resulting variable to 'error' - e.g., for z= y*A3, write z= 'error' if not defined. a) Using matrix multiplication, multiply A1 by A1, set to a b) Using matrix multiplication, multiply A1 by A1 transpose, set to b c) Using matrix multiplication, multiply A1 by v1, set toc d) Using matrix multiplication, multiply A1 transpose by v1, set to d e) Using matrix multiplication, multiply A1 by v1 transpose, set to e f) Using matrix multiplication, multiply A1 by A2, set to f g) Using matrix multiplication, multiply A1 transpose by A2, set to g h) Using matrix multiplication, multiply v1 transpose by v1, set to h i) Using matrix multiplication, multiply v1 by v1 tranpose, then subtract x from this result. Set final result to i j) First, let A3 = 2*ones(4,3) Next, multiply 2 by A1 transpose, then subtract A3 from the result; set the final result toj k) Using matrix multiplication, multiply v1 by j (from the previous problem). 3) Consider the series Liu 2i - Use vectors to compute the sum for n = 100, and set the result equal to the variable sum 100. In this case, array operation(s) may be u useful, as opposed to matrix operations
