Why won't Matlab plot anything?

When I try to plot anything, nothing comes up. There are no errors, there's just nothing.
>> x=-10:.1:10;
>> y=sin(x);
>> plot(x,y);
No figure window pops up.

You may have previous plot open somewhere and Matlab is plotting it on the same figure. Check for open figures, you might find it.
Alternatively, Use "close all" at the beginning and try again.
close all
x=-10:.1:10;
y=sin(x);
plot(x,y);

Try adding a line style to your plot function, such as
plot(x, y 'b-')
I've had a similar problem and this fixed it for me

You do not appear to have posted your code, which makes it difficult for us to tell you how to repair it. It is not at all productive for us to list all of the different ways that can possibly lead to a plot not working as expected.

q=5; s=0.002; b=20; n=0.03;
g=@(f) ((s*sqrt)*(b*h)^(5/3))/(n*(b+2*h)^(2/3))-q;
fplot(g,[0 1]), grid, xlabel('f'), ylabel('g(f)')
why it show nothing

You should get an error message that tells you why.
You created g as a function of f, but not only is it invariant on f, it's a function of h, which is undefined.
