The array is a row vector.

I can find the smallest element and its index using

Answer 1

I know this is an extremely late reply but I am hoping to help anyone who may have this question later.

If A is the array of elements, yu could try using the find function to determine the index of the n smallest elements.

[~, idx] = find(A > -Inf, n, 'first')

To determine the n largest elements,

[~, idx] = find(A < Inf, n, 'last')
