How to extract values from columns in a matrix

Dear members

I have this matrix (5*5) for example

H=[0 0 0 0 0;

0 1 0 0 0;

1 1 0 0 0;

1 0 1 0 0;

1 0 1 1 0]

I want to extract from each column, the corresponding value.

It means:

• from the first column, I want the first value. (which is 0)
• from the second column, I want the second value. (which is 1)
• from the third column, I want the third value. (which is 0)
• ........... etc

until the last column, I want the last value.

Please, how can I program this in MATLAB, especially that I want a general program for any matrix. Not specifically for this matrix.

Thank you.

H=[2 0 0 0 0;   % Smarter test data with 
   0 3 0 0 0;   % specific values on diagonal
   1 1 4 0 0;
   1 0 1 5 0;
   1 0 1 1 6];   

v = diag(H)

% Alternative:
v = H(1:size(H)+1:numel(H))

@Jan I could not find any way to direct massage you thats why i post my question in this thread.

sometime earlier i was using a "portable" matlab for learning purpose. I did not install it in my system and i needed any licence key. the whole set up i carried in a pen drive in a zip file. I unziped it and used it. however that model had some limitation. I need that type of IDE/ verson now (argent).

can you/ any one help me by providing that version name?

A "portable" Matlab version is not allowed by the license conditions, as far as I know. Then you are asking for an illegal installation.

thank you for sharing your knowledge.I am not using this installation and will try to solve my problem using Matlab online.
