repmat(col,2,1)

or

repmat(col,numel(row),1)

[Andrea]

but it does not work for other row and col: Please consider example below:

row=[1 2 3 4 5 6 7];

col=[ 537 538];

And I want b=[ 537 538; 537 538; 537 538; 537 538; 537 538; 537 538; 537 538]

can you please again help me?

I updated the answer. What you really need is 7 rows.

It works now. I have some little matrices with different size (such as 7*3, 2*5, 8*1,...) and I need to put them in a bigger matrix. My problem actually is I want similar arrays with similar row or col is put in the same position (array) in the bigger matrix. It actually have taken a lot of time until now and no matter how much I have spent on it, It still does not work!

You may want to start a new thread and explain the issue. I'm sure someone here can help.

row = [1 2];
col = [10 11 13];

b = ones(length(row),length(col));

clear m
for m = 1:length(row)
  b(m,:) = col;
end

It works for all row and col. Thanks a lot.
