MATLAB: Finding values in a matrix with logical operation

Question

Hi

I know how to show for a Matrix A the values in the first column which fullfill a certain condition. Say:

A =
       8     1     6
       3     5     7
       4     9     2

Then I could use for displaying all the values bigger then 3 in the first column the following line:

A(A(:,1) > 3)

But what line do I use, if I want to display the values in the second column which are bigger than say "3"?

Thanks

A strange question. What about replacing the column index 1 by 2?

A(A(:, 2) > 3, 2)

Explicitly:

v = A(:, 2);
v(v > 3)
