Is there a simple way to rearrange a matrix into a diagonally dominant form?

I have a matrix and I need to make sure that it is diagonally dominant, I need to do this by ONLY pivoting rows.

I can find codes to test for dominance in that they will check to make sure that the value in the diagonal is greater than the sum of the row, but I cant find anything on how make matlab recognize that it needs to pivot if the diagonal is not greater than the sum of the row

Answer 1

[Azzi Abdelmalek]

If I've understood your question

a=[1 2  3;4 5 6;7 8 9]
diag_som=trace(a)
mat_som=sum(a,2)
test=any(mat_som>diag_som)   % If test=1 then a is diagonally dominant

Answer 2

diag_som=trace(a) mat_som=sum(a,2)-diag(a) test=any(mat_som>=diag_som)
