MATLAB: How to take the X smaller values of an array

arrayMATLABsort

Hello everyone,
I have an array x (for example size(x)= 1, 10) and x=(1, 4, 100, 3, 14, 56, 8, 90, 23, 2).
My question is how can I keep the 6 smaller values of x without making a sort ? Because when I do a sort, it changes the place of the values.
For example if y is the output array I want that y=(1, 4, 3, 14, 8, 2)
Thanks for reading.

Best Answer

[y,idx] = sort( x );
[~,idx2] = sort( idx(1:6) );
y = y( idx2 );
There may be a slightly more elegant way, but that does the job.
