Finding 2nd minimum value in an array
显示 更早的评论
I want to find the 2nd minimum value in an array. min(A) can be used to find the minimum value, but I want to find the the number greater than minimum (2nd minimum). Can anyone help me in doing that???

A2 = sort(A(:));
out = A2(2);
other way:
A2 = unique(A(:));
out = A2(2);
or:
out = min(setdiff(A(:),min(A(:))));
etc.
