extracting an element in a vector
显示 更早的评论
there is a vector like A=[a b c d] and these a b c d are the numbers which I dont know the values. If I write max(A), then I find the max value element of this vector;and writing min(A), I can find the min element of this vector. but I want to create a new vector taking the two values of this A vector except these two max and min. I wanna take the other two element. so,how can i do this?
thanks so much.

[~,ii] = max(A);
[~,ii(2)] = min(A);
out = A(setdiff(1:numel(A),ii));
other way
[~,ii] = sort(A);
out = A(sort(ii(2:end-1)));
more way
out = A(A ~= max(A) & A ~= min(A));

If we have repititions max's and min's that answers between 1st and 3th ways or 2st and 3th ways are different:
>> A = [100 5 8 5 100];
>> [~,ii] = max(A);
[~,ii(2)] = min(A);
out1 = A(setdiff(1:numel(A),ii))
out1 =
8 5 100
>> [~,ii] = sort(A);
out2 = A(sort(ii(2:end-1)))
out2 =
8 5 100
>> out3 = A(A ~= max(A) & A ~= min(A))
out3 =
8
>>
