Correcting and optimizing Paulo's answer:

x=0:0.1:10;
s=semilogy(x,10.^x);
set(gca,'YTickLabel',num2str(get(gca,'YTick').'));

Ummm, 10 to the 1000 ??

Also, the labels so generated will be merely 0 2 4 6 8 10 rather than 1 100 10000 and so on.

Huh? This question is over 3 years old and asked by someone else, and doesn't appear to be related to your question. Maybe read this and post your own, new question.
