Problem in setting Yaxis value

I am using MATLAB 2015a. After going through the Q&A I finally wrote the command lines to set the Yaxis values as exponent, but its not working.

Here is the code

x = linspace(0,5,1000);
y = 100*exp(x).*sin(20*x);
plot(x,y)
ax = gca;
ax.YAxis.Exponent = 2;

Its showing this error "

No appropriate method, property, or field 'YAxis' for class
      'matlab.graphics.axis.Axes'.

        Error in rough6 (line 32)
        ax.YAxis.Exponent = 2;"

Please help me to convert the Yaxis value in desired exponent form.

Thanks

I don’t remember when that was introduced. It was obviously after R2015a.

One approach to a work-around:

x = linspace(0,5,1000);
y = 100*exp(x).*sin(20*x);
plot(x,y)
ax = gca;
% ax.YAxis.Exponent = 2;
yt = ax.YTick;
xpnt = 2;
new_tick_lbls = 10.^log10((10^-xpnt)*abs(yt)).*sign(yt);
ytlblc = sprintfc('%.0f',new_tick_lbls);                                % Undocumented: ‘sprintfc’;                                    % Undocumented: ‘sprintfc’
ax.YTickLabel = ytlblc;
text(min(xlim), max(ylim)*1.05, sprintf('\\times10^{%.0f}', xpnt))

Experiment to get the result you want.

Try this - note that it relies on the hidden/undocumented axis property YRuler (and similarly for XRuler, ZRuler):

ax.YRuler.Exponent = 2;

This works from R2014b onward. Starting in R2015b you can use YAxis instead of YRuler, but YRuler can still be used to this day as a synonym. If you want to take a careful approach in case YRuler will someday stop working, do this:

try
   ax.YAxis.Exponent = 2;
catch
   ax.YRuler.Exponent = 2;
end
