Hello,
How can I pick up the argmin of a vector? I.e. In a vector such as a=[2 3 1 4 5], I want to pick up 1 by min(a) and also want to have 3 that is the Nth element of this vector with the minimum 1. I tried to use find(a=min(a)) but the find operator is not working with equality.
Thanks

From the documentation for the min function:
[C,I] = min(...) finds the indices of the minimum values of A, and returns them in output vector I. If there are several identical minimum values, the index of the first one found is returned.

If find is not working with equality then your values are probably not what you think they are:

The expression find(a=min(a)) is not valid. Try using == (which is used when testing equality) instead of = (which sets the left hand side equal to the right). find(a==min(a)) should work.
