Hello,
If I have an array for example: A=[10 11 12 1 8 9 1 3 5] and I use the '[C,I]=min' function to find the minimum value of the array. But if the array has two or more same minimum values, the MIN function always return the first value!How can I get the last minimum value of an array?In my example, I want the 7th value 1 of array A and not the 4th.However, I want this function to work for random arrays and not only for array A.
Thank you..!!

find(A==min(A))
will get them all. Then you can choose whichever you like. To get just the last one
find(A==min(A),1,'last')

My rough idea is along the lines of sorting the vector first (with saving the indices) and then identify the last minimum.

If you only want the last one, you could use
[v, ind] = min(A(end:-1:1));
ind = 1 + length(A) - ind;
