I nedd help to scale the y-axis of Gaussian pdf
for example:
x = linspace(-20,20);
plot(x,normpdf(x,4,4))
How can I plot the histogram of this example?

x = linspace(-20,20);
y = normpdf(x, 4, 4);
plot(x,y)
histogram(y, 10)

Sure.
x = linspace(-20,20);
y = normpdf(x, 4, 4);
plot(x,y)
hold on
histogram(y, 10)
hold off
Not very useful, though.

I suspect that you are looking for something like the following, but notice that it is exactly opposite to what you asked for.
r = normrnd(10,1,100,1);
histfit(r)

Simply googling "matlab histogram" would have answered your question.
That link is for the documentation for histogram.
histogram(normpdf(x,4,4))
will do what you want.
