Find indicies of k smallest matrix elements

11 views (last 30 days)
I'm trying to find the indicies of smallest k matrix elements.
For example if I have
A = [10 5 2; 34 5 21; 4 6 8];
and I want to find the smallest 2 elements indicies then I want indicies 7 and 3.

[~, indices] = sort(A(:), 'ascend');
ind = indices(1:k);

[~,idx] = mink(A,2);

I'm using R2020b, that's the newest isn't it?
mink gives minimums over a dimension, not the whole matrix. Sindar's code doesn't work for my example above.
