upper=[54.48 62.83 46.53 44.11 46.33 49.95 53.68 58.03 62.99 69.33];

lower=[54.48 45.65 40.37 40.87 42.38 44.99 47.65 50.70 53.92 57.89];

fliplr() flips the vector left to right.

patch() plots the colored patch between the lines.

x = [t, fliplr(t)];          % t is a row vector
y = [lower, fliplr(upper)];  % lower and upper are row vectors
patch(x,y,'green')
