31. Create the following vector C. C = [0.7 1.9 3.1 4.3 5.5 6.7 7.9 9.1 10.3 11.5 12.7 13.9 15.1 16.3 17.5] Then use MATLAB's built-in reshape function and the transpose operation to create the following matrix D from the vector C: Use the matrix D to: 0.7 1.9 3.1 4.3 5.5 D= 6.7 7.9 9.1 10.3 11.5 12.7 13.9 15.1 16.3 17.5 (a) Create a nine-element column vector named ua that contains the ele- ments of the first, third, and fourth columns of D. (b) Create an eight-element raw vector named ub that contains the elements of the second row of D and the third column of D. (c) Create a six-element row vector named uc that contains the first three ele- ments of the first row of D and the last three elements of the last row of D. 31. Create the following vector C.
