How can we plot a function with the domain involving infinity? Suppose I want to plot the following function:
f(y)=(2*pi*y)^(-1/2)*exp(-y/2); y>0
How can I do this in MATLAB?

Of course, you can't plot the whole thing, but you can plot enough so that it's obvious where the curve is going. One approach is to let MATLAB choose the domain for you:
f = @(y) (2*pi*y).^(-1/2).*exp(-y/2);
