Choose some data that has a minimum value

hello all,,

i wanna asking about how to choose some data that has a minimum value,,

example :

i do input five data

i've knew that if choose minimum data in matlab use "min" command

but it just give one value

i want in my case, it can choose three data that has minimum value

can someone help me??

this is my code

a= input ('Input Number of Data :');

for c=1:a

        int2 = ['Input The First Score - ',num2str(c),' :'];

        int3 = ['Input The Second Score - ',num2str(c),' :'];

        b(c,1) = input(int2);  

        b(c,2) = input(int3);

    end;

   for d = 1 : 1

        int4= ['Input The First Data :'];

        int5 = ['Input The Second Data :'];

        e(d,1) = input(int4);  

        e(d,2) = input(int5);

   end;

    x = ( b(:,1) - e(1,1)).^2 + (b(:,2) - e(1,2)).^2;

    disp(x)

x=[4 1 3 8 2 0 10]
a=sort(x);        % sort x in ascending order
min_value=a(1:3)  % choose the 3 first lowest numbers

if in my case the data has category so how to choose majority category

example :

First | Second | Total |Category

7     | 7  | 16   |Bad

7     | 4  | 25   |Bad

3     | 4  | 9    |Good

1     | 4  | 13   |Good

if i use function min value that u give to me before then the chosen data is data(1),data(3) and data(4) with one category is bad and two category is good

i wanna my final result is chosen by majority category of data

so the final result is "The new data's class is Good"

majority category data is "good" bcoz two data have category "good" and one data have category "bad"

so category "good" is chosen and bad is not chosen

how to make it?
