How do I change the axis exponent of several subplots at once?

Hello,

I was wondering if there is a way to change the exponent value of several subplots (all subplots within a figure) at once.

Currently I'm using:

(source: https://nl.mathworks.com/help/matlab/creating_plots/change-tick-marks-and-tick-labels-of-graph-1.html#d119e2453)

ax = gca;
ax.YAxis.Exponent = 3;

This has to be done to each subplot seperately.

I have tried using:

arrayfun(@(x) YAxis.Exponent(x,3), findobj(gcf,'Type','axes'))

and:

arrayfun(@(x) Exponent(x,3), findobj(gcf,'Type','axes'))

Neither work since Matlab doesn't recognize the functions. Error:

Unrecognized function or variable 'exponent'.

Error in @(x)exponent(x,0)

I think something similar to what I've tried is possible, but I don't know what to put instead of "YAxis.Exponent".

Thank you.

arrayfun(@(axH) set(axH.YAxis, 'Exponent', 3), findobj(gcf,'Type','axes'))

Alternatively:

AxesH = findobj(gcf,'Type','axes');
set([axesH.YAxis], 'Exponent', 6);

Remember that gca and gcf is fragile: As soon as the user clicks on a different figure, unexpected handles are replied. Prefer to store the handles of the axes objects explicitly, e.g.:

AxesH = gobjects(1, 6);
for k = 1:6
    AxesH(k) = subplot(2, 3, k);
    ...
end

Nice use of structure expansion.

Thank you, exactly what I was looking for.

I am aware that gca and gcf are fragile, thanks for the heads up though.

subplot(2,1,1); plot(randn(1,20) * 1e5)
subplot(2,1,2); plot(randn(1,20) * 1e5)

yax = get(findobj(gcf,'Type','axes'), 'YAxis');
set([yax{:}], 'Exponent', 3)

Thank you, this also worked well.
