Make elements outside of a threshold NaN in an array

I'm working on a function that runs through an array and elements outside a certain threshold become NaN. Although I can't get the elements above/below the threshold to be omitted (NaN).

function [p] = filtering(fc,thresh1,thresh2)
p = fc;

% Set threshold
for i = 1:fc
    if fc >=thresh2
        p = NaN;
    elseif fc <= thresh1
        p = NaN;
    else
        continue
    end
end    
end

Thanks in advance!!

p = fc;
p(p <= thresh1 | p >= thresh2) = NaN;
