Hi, This might be such a silly question but could anyone please help? I get a 3D matrix A(n,m,k) so I want to take the value a(:,1)=A(1,1,:). But Matlab doesn't allow me to do that. Is using "for" loop the only way to do that?

You could accomplish that with:
a = reshape(permute(A,[3,1,2]),size(A,3),[]);
[Note: You really haven’t specified how the first two dimensions in A should be arranged in the single second dimension of a. Here I have taken the default arrangement.]

For the example you gave, the following also works:
a=squeeze(A(1,1,:));
