I am not able to fill with the color between 2 lines in matlab

% I am not able to fill with the colour between 2 lines (y1 and y2) in Matlab. The Matlab code is attached as follows:

close
x = (0:60)';
y1 = 0.5025*exp(0.0471*x); y2=0.2045*exp(0.02*x);
hold all
plot(x,y1)
plot(x,y2)
patch([x fliplr(x)], [y1 fliplr(y2)], 'c','EdgeColor','none', 'FaceAlpha',0.25)

Since x (and consequently y1 and y2) are column vectors, using fliplr does not have the desired effect. Instead you can use flipud or the more general flip. And use vertical concatentation (i.e., [x; flip(x)]) rather than horizontal concatenation (i.e., [x flip(x)]).

close
x = (0:60)';
y1 = 0.5025*exp(0.0471*x); y2=0.2045*exp(0.02*x);
hold all
plot(x,y1)
plot(x,y2)
patch([x; flip(x)], [y1; flip(y2)], 'c','EdgeColor','none', 'FaceAlpha',0.25)
