How do I use an unusual base in a semilogx plot?

Is it possible to plot data against an x-axis with a log base 1.85 axis? The default is log base 10, and I've found a way to do log base 2, but not odd values.
Thanks!

See if this works for what you want to do:
x = 1:5;
y = 1.85.^x;
figure
subplot(2,1,1)
semilogx(x, y) % Original Plot
grid
subplot(2,1,2)
semilogx(x, y)
grid
Ax = gca;
xt = Ax.XTick;
xtl = compose('%.1f', log10(xt)./log10(1.85));
Ax.XTickLabel = xtl; % New ‘x’-Axis LAbels
Check = 1.85.^(log10(xt)./log10(1.85)); % Check Appropriate Conversion (Delete)
.
