In the live editor, I can get multiple plots together. For example:

x=1:100;
y1=x;
y2=x.^2;
y3=x.^3;
plot(x,y1)
plot(x,y2)
plot(x,y3)

Then I can get the following result:

Now, my question is "how can I change the all font size in the three plots?"

I can get the result I want by adding the codes as below:

x=1:100;
y1=x;
y2=x.^2;
y3=x.^3;
plot(x,y1)
set(gca,'FontSize',15)
plot(x,y2)
set(gca,'FontSize',15)
plot(x,y3)
set(gca,'FontSize',15)

but I don't want to write the code to change the font size many times.

I want a simpler way to change the font size, or the way to change the default font size in plots.

set(findobj(groot, 'type', 'axes'), 'FontSize', 15)

I tried adding your code to my script in the question, but the result is as below:

The font size of only the third plot became bigger. Where did I go wrong?

Anyway, I found the way to change the default font size by the following code:

set(0,'DefaultAxesFontSize', 15)

I was able to change the default font size by using this. Thank you.

Livescript creates a new axes for each plot, and it appears to hide some of them. You would need to change the findobj to findall
