color area between functions

Hi,

I have two functions g = exp(-x.^2./2) and h = x.^2-3.*x+2;

there is a region enclosed between them, between x=0 and x=3

I wanna color it using fill

how to? =)

x = -1:.01:4;
g = exp(-x.^2./2);
h = x.^2-3.*x+2;
plot(x, g, 'r', 'LineWidth', 2);
hold on;
plot(x, h, 'b', 'LineWidth', 2);
x=.43:.01:2.08;
x2 = [x, fliplr(x)];
g = exp(-x.^2./2);
h = x.^2-3.*x+2;
inBetween = [g, fliplr(h)];
fill(x2, inBetween, 'g');
