MATLAB: Reversing the order of EVEN rows in an array

Question

I have a matrix D that consists of 12 cols and 8 rows.

How can I reverse the order of even rows.

i.e. for a simplifeid 4,3 case

>> d=rand(4,3)
d =
    0.1067    0.8173    0.2599
    0.9619    0.8687    0.8001
    0.0046    0.0844    0.4314
    0.7749    0.3998    0.9106
    

I want it to appear as:

    d =
    0.1067    0.8173    0.2599
    0.8001    0.8687    0.9619      
    0.0046    0.0844    0.4314
    0.9106    0.3998    0.7749 

Answer 1

d(2:2:end, :) = fliplr(d(2:2:end, :));
