You may be able to modify this to suit your needs:
x = linspace(0,1,20)';
y = sin(x);
dy = .1*(1+rand(size(y))).*y; % made-up error values
fill([x;flipud(x)],[y-dy;flipud(y+dy)],[.9 .9 .9],'linestyle','none');
line(x,y)

WOW. Thanks. No file downloads, no mess, no fuss, no fretting about learning another programming language or environment, or exporting a bunch of data elsewhere...Just five simple lines of code and the relief of saving a whole lot of tedium to make something seemingly simple work!

You can choose one of the following in the FEX:
User defined functions have to be placed into a folder and that folder should be added to the MATLAB path. See addpath(), savepath() or on the menu bar File > Set path
