Ex: A=[1 2 3;4 5 6];
I want to run a for loop for this matrix to compare a RANDOM element like
A(i,j)>=A(i,j+1) for the total elements but randomly, basically choosing an element A(i,j) randomly and compare it with A(i,j+1) but I need to cmpare all the elements in the matrix (6 elements )
Thank you in advance

A=[1 2 3;4 5 6];
a=A<=A(randi(numel(A)));

If you take a random element of A.
A(randi(numel(A)))
and compare it to A (all elements), you get a logical matrix where logical 1 element meets the condition and logical 0 does not.
A<=A(randi(numel(A)));
