find all minimum elements of 2 dimensional array in Matlab

Having 2-dimensional array,A, I want to find minimum number in the array. However I can have more than one of that number. How can I find the [row col] of all minimum value? Example:

2 3 4 2
1 6 7 1
9 8 3 1

It should return [2,1] [2,4] [3,4]

Solution

  • find will do the trick: 

    [I,J] = find(A == min(A(:)) );

disp([I J])
   2   1
   2   4
   3   4
