I have n*n matrix.I want to get all the elements of 1st column of nth rows like A(:,1). Now how will i arrange all the n elements into a single row i,e b=[A(1,1) A(2,1) A(3,1)............ A(n,1)].What will be the command for n being large say 5000?

If A is real, there is no difference in the result. If A is complex, then ' will conjugate the elements (i.e., negate the imaginary part), whereas .' will not conjugate the elements.
