x=[0.1:0.1:5];
y=(sin(x))/x;
figure(2)
grid on
plot(x,y)

It's an error in your calcuation of y. Check the size and you'll see it's coming out as a scalar. Replace "/" with "./", since you want element-wise division.

Because you are calculating a single point.
If you use element-wise division here (using ./ rather than /), you get the plot you expect:
x=[0.1:0.1:5];
y=(sin(x))./x;
figure(2)
grid on
plot(x,y)
See the documentation on Array vs. Matrix Operations (link) for an extended discussion.
