6. Calculate the following scalars, matrices and vectors, using the matrices from problem 5 Outputs of the commands are required. (mean, sum, det, find, transpose (aka the apostrophe operator)) C2-sum of all the elements of the 2x2 matrix at the bottom right corner of the matrix C sqA (A) A ( indicates transpose) detsqA-sqA (determinant of sqA) Given that the formula for calculating the determinant of a 2x2 matrix: A= is: det(A) = ad-bc Verify the above answer for detsqA by directly computing it using matrix indexing. Store your result to a variable named my detsqA. my _detsqA-use Matlab matrix indexing to compute this directly (without using det0) saB-B(B)T meanB_row1 mean value of the elements of first row of matrix B. mid-the 2x2 matrix in the middle of the matrix C lthindex-find the indices of the elements in matrix C that are less than 0.5 lth=a vector that contains a list of variables that are less than 0.5 in matrix C. imsaA = sqAi (inverse of the matrix sqA)
