for example
a=[1 2 3; 4 5 6];
b=max(min(a);
what i want,
for min(a)=[1 4]' , index(1,1 2,1)
b=max(min(a))= 4 , index as 2,1
how can i do this? i require the final index as said above. what is the code for it.

Praveen, use something like
ind = arrayfun(@(ii) find(a(ii,:)==min(a(ii,:),[],2)),1:size(a,1));
to get the column indices of the row minima, and
[r c] = find(a == max(min(a,[],2)));

thank you for your response,
i used [k,v]=max(min(b));
where k gives the value and v gives the index. for my problem this was enough as
min(a)=[1 2 3] [k,v]=max(min(b)); output : k=3 v=3. this one solved my problem. thank you for your other choices , i will try them in future.
