MATLAB: Elements of a vector whose difference is minimum

minimialization

Is it possible to find the elements of a vector whose difference is minimum?

Best Answer

If v is the given vector,

N=length(v);
G=abs(bsxfun(@minus,v(:),v(:).'));
 G(1:N+1:end)=nan;
[i,j]=find(G==min(G(:)));
v(i), v(j)

The red markers in the right column indicates that something is seriously wrong

Right click function

(There is already a function named sort in Matlab. Pick another name. )

Remove the first line (and add end as the last line).

Try

function y = my_sort( v )
    n = length( v );
    sorted = 0;
    k = 0;
    
    while ~sorted
        sorted = 1;
        k = k + 1;
        for j = 1:n-k
            if v(j) > v(j + 1)
                t = v(j);
                v(j) = v(j + 1);
                v(j + 1) = t;
                sorted = 0;
            end
        end
    end
    y = x;
end

I get

Cannot find an exact (case-sensitive) match for 'x
The closest match is: X in H:\m\cssm\X.m
Error in my_sort (line 19)
    y = x;

Replace

    y = x;

    y = v;

and try again

>> my_sort( randi(12,1,6) )
ans =
     2     4     7    12    12    12
>>
