# logarithmic x-Axis for a function handle

Hi, I got a question regarding the plot of two function handles. I have this function handles:
The first one: n=@(R) 1./(3.*pi.*R_e.^3.*R_dach).*(R_e./R_dach).^(-2/3).*(R.*(R_e-R_stern))./(R-R_stern).*(A_2.*R+A_3)./(A_2.*R_e+A_3).*exp(B_1®+B_2®);
The second one: N=@(R) 1./(3.*pi.*R.^2.*R_dach).*(R_e./R_dach).^(-2/3);
And I'd like to plot both function handles, but the x-axis should be logarithmic. n® should go from R_stern to R_e and N® should go from R_e to R_dach. They have the same value for R=R_e (N(R_e)=n(R_e). So something like
fplot(n, [R_stern R_e])
hold on
fplot(N, [R_e R_dach])
hold off
But with a logarithmic x-Axis.
Could anyone help me with the solution of my problem? I attached the .m file, so feel free to try out :) Thanks in advance and best regards, Karsten

Try this:
fplot(n, [R_stern R_e])
hold on
fplot(N, [R_e R_dach])
hold off
set(gca, 'XScale','log')

My pleasure.
