I have this matrix,

A = [0.1 0.2 0.3 ;
     0.4 0.5 0.6 ;
     0.7 0.8 0.9];

I want to find min(A,[],1), but them I want it to tell me the row and column that the min value falls on. Any ideas?

PS, the values are arbitrary. I was just using that as an example. I now realize that it's a terrible example for this problem.

[v,idx] = min(A,[],1)
out = [v;idx;1:size(A,2)]

absolute min

[v,I] = min(A(:));
[ir,jc] = ind2sub(size(A),I);
out = [v,ir,jc];
