plotting with semilogy

Hi all,

How can I plot different rows of a matrix with different colors all in one semilogy calling?
Like this:
semilogy(dbs, BER([1,5],:), 'go-',...
    BER([2,4],:), 'blo-',...
    BER(3,:), 'ro-');

Can somebody tell me what is the correct syntax to do so?

Thanks,
Elnaz
