I am a matrix of size A= rand(100,1)
I want to generate matrix by extracting 2 rows in interval of 5.
B=A([1:2,6:7,11:12,16:17,........,96:97],:).
Could anyone help me to write in the simplified form to execute in matlab.

row_idx = reshape((1:5:100) + [0;1],1,[])

?? row_idx is already a separate matrix. You take it and
B = A(row_idx,:);

For 2, 3, 4 of each group of 5,
row_idx = reshape((1:5:100) + [1;2;3],1,[])
