    %% Modify Error Bars After Creation
% Create a line plot with error bars. Assign the errorbar object to the
% variable |e|.

x = linspace(0,10,10);
y = sin(x/2);
err = 0.3*ones(size(y));
e = errorbar(x,y,err)

%%
% Use |e| to access properties of the errorbar object after it is created.
% Starting in R2014b, you can use dot notation to set properties. If you
% are using an earlier release, use the |set| function instead.

e.Marker = '*';
e.MarkerSize = 10;
e.Color = 'red';
e.CapSize = 15;
