How to make subplots from plots generated from toolbox functions.

Hi everyone,

I would like to make figures with subplots that are generated from a toolbox function. I use a function from the signal processing toolbox as an example. Here are two plots that plot separately into their own figures:

if true
  % code
load train
findchangepts(y,'MaxNumChanges',6,'Statistic','rms');
figure
findchangepts(y,'MaxNumChanges',6);
end

and here is my attempt at putting them into one figure:

if true
  % code
load train
p1=findchangepts(y,'MaxNumChanges',6,'Statistic','rms');
figure
p2=findchangepts(y,'MaxNumChanges',6);
subplot(2,1,1)
plot(p1)
title('first')
subplot(2,1,2)
plot(p2)
title('second')
end

the failed figure I get is:

thanks in advance.

Hi, I'm looking for an answer for your quesion too but what I know is that p1 and p2 here return the index at which the mean of x changes most significantly. So I think plotting p1 and p2 is meaningless.
