please illustrate with a input and the desired output as text instead of picture

The matrix:

[a a a a a;

b b b b b;

c c c c c;

d d d d d;

e e e e e ;

f f f f f ]

should be converted to:

[a a a a a ;

c c c c c;

e e e e e ;

b b b b b;

d d d d d ;

f f f f f];

You should learn about indexing, one of the most essential aspects of Matlab:

M = randi(4,10,5) ; M(:,1) = 1:size(M,1) % example data
M2 = M([1:2:end 2:2:end], :) % re-ordering the rows
