find all minimum elements of 2 dimensional array in Matlab

问题

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]

回答1:

find will do the trick:

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

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

回答2:

I belive this should work

[row,col]=find(a==min(a(:)))

where a is your matrix. Find can also output a linear index if you give just one output.
