Not sure the effect you're really after but

set(gca,'YTick',[1 2 4 8 16 18])

which can be

    set(gca,'YTick',[2.^[0:4] 18])

if you're looking for more concise formulation for the values.

If you intend the ticks to be spaced evenly but labeled otherwise, have to use N (in this case 6) tick values spaced as desired and then 'xticklabel' to write the desired label value at the respective location.
