MATLAB: How to find index of a minimum value starting from the end

indexingMATLABmatrix

I have this code:
 A =
     1     2     3     4     5     6     7     8     9     1     1     1     1
     1     2     3     4     5     6     7     8     9     1     1     1     9
     1     2     3     4     5     6     7     8     9     1     1     2     3
     1     2     3     4     5     6     7     8     9     1     1     1     1
     1     2     3     4     5     6     7     8     9     1     1     1     5
     1     2     3     4     5     6     7     8     9     1     1     1     3
     1     2     3     4     5     6     7     8     9     1     1     2     3
B = min(A')
B =
     1     1     1     1     1     1     1
index = find(A'==B, 1, 'last')
index =
    89
What I want is to get the indices of the smallest number starting from the end of each row. The answer should look like this
index =
13 12 11 13 12 12 11
Thanks, George.

A = randi(10,10);
A_min = min(A,[],2);
dummy = bsxfun(@eq,A,A_min);
dummy = bsxfun(@times,dummy,1:size(A,2));
result = max(dummy,[],2)
