Shading Between Two Lines

I have a plot with two lines on it, as seen below. To get these lines, I've plotted the following.
plot(HH, LWAC, '-')
hold on
plot(HH, LWAR, '-')
HH is a wind speed value from 4-20. LWAC and LWAR are both separate vectors of y-values.
What I need to do is have MATLAB shade between the two lines. How can I go about doing that?

It would be easier with your data.
Assuming that all the vectors are coiumn vectors —
HH = linspace(4, 20).';
LWAC = 10*(1 - exp(-0.1*HH)) + 92;
LWAR = 10*(1 - exp(-0.1*HH)) + 94;
patch([HH; flip(HH)], [LWAC; flip(LWAR)], [1 1 1]*0.8, 'EdgeColor','none')
hold on
plot(HH, LWAC, '-')
plot(HH, LWAR, '-')
hold off
That should do what you want. Experiment to get different results.

See the documentation on patch for details.
