how will i arrange the matrix?

 a=[4 6 4; 3 7 9; 3 0 1; 4 7 9;0 1 3]

The entropy value is 0.5665

I want to reduce the entropy after arranging the a?

[Jos (10584)]

How do you calculate the entropy? And how would you like to arrange a (swap rows only, columns only, or all)?

[Roger Stafford]

No matter what base is used for the logarithm, the entropy I compute for your matrix does not come out as 0.5665 . Moreover, the computed entropy is always independent of how the matrix may be rearranged. For that reason it is important that you tell us what definition you use in computing the entropy of such a matrix that makes it dependent on arrangement.

just execute the command

entropy(a) in workspace

Sort you matrix using the built-in function sort:
