For integer xlabel and ylabel (e.g. 362093) put the following line after you set xlabel or ylabel:
set(gca, 'YTickLabel', sprintf('%7d|', get(gca,'YTick')))
- up to 7 integer digits on y-axis.
Matlab default behavior, which Mathworks says is currently not changeable, is to put exponential format into xlabel and ylabel for large numbers–even integers.
