Return a figures from different functions and subplot them

I have three functions, these function generates 3 different plots. Now I want to subplot them from my main script.
How can I do it?

If your three functions are a, b, c; then your script could be:
subplot(3,1,1);
a;
subplot(3,1,2);
b;
subplot(3,1,3);
c;

I have tried it. but didn't work. here is my function formate:
NB: I want to plot the figure for two time. one is from function itself. Another is from main script with subplot.
function [y, h1] = func1(x)
y = sin(x);
figure();
h1 = plot(x, y)
end

Your function returns the line handes. If you record them, then you can take each handle and set its Parent property to be the axes that you want the line to appear in. For example,
[y1, h1] = func1(x1);
[y2, h2] = func2(x2);
ax1 = h1.Parent;
ax2 = h2.Parent;
fig1 = ax1.Parent;
fig2 = ax2.Parent;
spax1 = subplot(1,2,1);
h1.Parent = spax1;
spax2 = subplot(1,2,2);
h2.Parent = spax2;
delete(fig1);
delete(fig2);

I tried your code. but it showing the following error.
>> ax1 = h_c.Parent;
>> ax2 = h_r.Parent;
>> fig1 = ax1.Parent;
>> fig2 = ax2.Parent;
>> spax1 = subplot(1,2,1);
>> h_c.Parent = spax1;
Axes cannot be a parent.

What is h_c and h_r ? And are you still using the code
function [y, h1] = func1(x)
y = sin(x);
figure();
h1 = plot(x, y)
end
That will return a Chart Line handle in the second output. If h_c is a chart line object, then it should be fine to set spax1 as its parent.
