logexample.fig

I have specified the limits of my x and y axis which are both on log scales. I want to also specify the intervals for the yaxes so that the intervals match across subplot (even if the scales are different). I am running into issues since the interval size is not consistent on a log scale...

I have attached the plot I currently get. I would like to have y labels at each whole number power of 10.

N = 500;
x = sort(1e3*rand(N,1));
y = sort(1e6*rand(N,1));
figure
loglog(x,y)
set(gca,'XLim',[1e1 1e4],'XTick',10.^(1:4), ...
        'YLim',[1e3 1e6],'YTick',10.^(3:6))
