Scientific notation values to the y axis label based on original data

Hey! I would like to automatically have the y-axis label updated based on the input values for the variable y. In this case I would like the line "-5" in the y-axis label replaced by "10^-5" (with the -5 shown as an exponent).
Thanks in advance for any help!
if true
% code
x=[1:3];
y=[.00002 .00004 .00006];
figure;
plot(x,y);
ylabexp=floor(log10(y(1)));
ylab = {'\uparrow';'\epsilon /';ylabexp;'M^{-1}'};
yh = ylabel(ylab);
set(yh,'rot',0)
ylabh2 = get(gca,'YLabel');
set(ylabh2,'Position',get(ylabh2,'Position') - [.1 0 0])
end

I tried to run your code but couldn’t.
- PLEASE format your code — use the ‘[{}Code]’ button
- what is ‘yval’?
- Y not use semilogy?

Change your ylabexp line to:
ylabexp=sprintf('10^{%d}',floor(log10(y(1))));
If I understand your question correctly, that should do what you want.
