Given the 3 x 4 matrix G below, how would you (using Matlab formulas): a. Use Matlab to create a new matrix H that represents G with its 2nd row completely deleted (a 2 x 4 matrix) b. Use Matlab to create a new vector w that represents the sum of each column of G. c. Use Matlab to create a 2 x 2 array J that is equal to rows 2 and 3 of columns 2 and 3. d. Use Matlab to create a new 3 x 1 vector k that represents the sum of each row -3 7 -89 G5 12 4 -3 1 27-6
