Edit

A=randi(100,4,4)
[val,id]=sort(A(:),'descend')
max_val=val(1:5)
id=id(1:5)
[ii,jj]=ind2sub(size(A),id)

EDIT

A = rand(5)
[id,id] = sort(A,2)
minrowloc = id(:,1)
maxrowloc = id(:,end)

MATLAB: Add uniform random number to matrix

I am not certain what you are asking.

If you want to add different uniform random numbers with a minimum value of 1 and a maximum value of 3 to every element in ‘A’, you have to tell the unifrnd function to create a matrix the size of ‘A’.

Try this:

A=[1,2;2,4];
[r,c] = size(A);
uniform_test=unifrnd(1,3,r,c);                      % Random Matrix (Size Of ‘A’)
Anew = A + uniform_test
