Hello all! I have some ambiguity with MATLAB. I saved my matrix as A(:,:,1) in workspace. Now I want to access column or some entries of my big matrix on command window.

I have the following loop.
for i=1:4
A(:,:,i)=i*ones(4,4);
end
Now I want second rows of A(:,:,i) i.e second row of A(:,:,1), second row of A(:,:,2), second row of A(:,:,3) and second row of A(:,:,4).

Do by following code
for i=1:4
A(:,:,i)=i*ones(4,4);
end
B = permute(A,[3,2,1]);
B(:,:,2)
The result is
ans =
1 1 1 1
2 2 2 2
3 3 3 3
4 4 4 4

Hi, Teshome Kumsa,
Follow pdb's answer. And transpose it.
B=squeeze(A(2,:,:))'; % B is what you want
Also without using squeeze, you can achieve it by
B = reshape(A(2,:,:), size(A,2), size(A,3))';

B=squeeze(A(2,:,:));
