That function is indeed the one you're looking for. Please post the complete error message (so all red text) and/or a piece of standalone code that we can run to reproduce the error.
Show the code and the error otherwise what help are you expecting to get?!

There are two easy ways to do this. First you can pass the values, but instead of directly the values pass their log, i.e.
plot(log(x), log(y))
The other way is through the handles
hPlot = plot(x,y);
and then modify the properties of the axes:
hPlot.xscale = 'log';
hPlot.yscale = 'log';
you can always change back to 'linear' if needed.

The loglog function will do that second automatically.
thanks for your answer
I have use
plot(X, Y);
semilogx(X, Y);
loglog(X,Y);
Now working perfectly.
