this is your assignment? What are the things you tried so far? where are you facing problem?

It is your homework, and you should solve it.

[Santos Solpos]

No idea

[Santos Solpos]

Can you give me a hint

[Walter Roberson]

Look at the top right corner of T, the part starting from 1 2 3 4 . Look at that 4 x 4 block. Now look at your variables. Do you see that same 4 x 4 block in any of your variables?

Hello Sir David Hill

Can you check my answers? I attached pdf of my answers to matlab problems. I am hoping that you will give a comment.

[Walter Roberson]

The division questions are ambiguous B/2C can be interpreted as B/2*C or as B/(2*C) depending on the context and the font.

AB can be either matrix multiplication * or element-by-element multiplication .* which are different operators.

B/C can be either matrix division / or element-by-element division ./

Answer 2

[David Hill]

Hint

T=[A,2*B,3*B+E;F-2*B,C,D];

[Steven Lord]

If a problem sounds like a homework assignment (which this absolutely does), please don't simply provide the answer! [The more work the student shows the more generous I would be with hints; if they'd posted what you did except wrote F+2*B instead of F-2*B I'd just go ahead and fix it for them.]

A hint would have been a pointer to some of the introductory documentation, like the Matrices and Arrays section of the Getting Started with MATLAB chapter.

Hello David Hill

I tried using blkdiag. Is it correct?

[David Hill]

I gave you the answer.

[Walter Roberson]

It would be possible to use blkdiag() in a solution, but the rest of the solution would mostly consist of working around the fact that you had used blkdiag()
