I have matrix of A . I need to select the 2nd, 4th and 6th row. How can I write that in MATLAB code?

B = [A(2,:);A(4,:);A(6,:)]
or if you want the rows one by one:
A2 = A(2,:);
A4 = A(4,:);
A6 = A(6,:);

See this page of the doc to learn about array indexing.
Hint: A(__,:) where the blank is a vector of row indicies.

I think I found out the way. It has to be something like this:
B=A([2, 4, 6], :)
