Please output the fifth largest number from a two-dimensional matrix with more than 5 elements and no repeated values.
%%Problem 2
disp('PROBELM 2')
disp('Random matrix A')
A=rand(3,3)
B=unique(A)
I am stuck after making the matrix. Any help would be appreciated.

when you specify n as 5 the last number in the result is the fifth largest number

B=unique(A);
% 'unique' also sorts A in the ascending order.
disp(B(end-4))
