Help me to solve the question

Create the following matrix B.

21 12 33 14 51 61

B = 17 18 19 10 11 12

19 14 11 13 15 20

Use the matrix B to:

(a) Create a 2 x 4 matrix C such that its first row includes the first two elements and the last two

elements of the first row of B and the second row of C includes the second through the fifth

elements of the third row of B.

(b) Create a 3 x 3 matrix D such that the first, second, and third rows are the first, fourth, and sixth

columns of matrix B

Hi Teresa,

Here is the solution of the 2 tasks you mentioned:

% Define the matrix B
B = [21 12 33 14 51 61;
     17 18 19 10 11 12;
     19 14 11 13 15 20];

% (a) Create matrix C
C = [B(1, [1, 2, 5, 6]);
     B(3, 2:5)];

% (b) Create matrix D
D = B(:, [1, 4, 6]);

% Display the results
disp('Matrix C:');

Matrix C:

disp(C);

    21    12    51    61
    14    11    13    15

disp('Matrix D:');

Matrix D:

disp(D);

    21    14    61
    17    10    12
    19    13    20

Please don't do student homeworks for them. When no effort has been made, then the student will learn nothing form your efforts, except that there is some sucker willing to do their homework.

You hurt the forum, since now @TERESA has seen that someone will step forwards wnd write their complete assignment for them. And that makes the student keep on doing the same.
