How to get MATLAB to display the index of the minimum value in a 2D array?

Question

I\'m trying to write a script in MATLAB that finds the location of the minimum value of a 2D array of numbers. I am certain there is only 1 minimum in this array, so having

Answer 1

As an alternative version, combine min to get the minimum value and find to return the index, if you've already calculated the minimum then just use find.

>> a=magic(30);
>> [r,c]=find(a==min(min(a)))

r =
     1
c =
     8

Or depending on how you want to use the location information you may want to define it with a logical array instead, in which case logical addressing can be used to give you a truth table.

>> a=magic(30);
>> locn=(a==min(min(a)));
