shadow the area between two curves in a plot

in my figure i have plottet 3 curves. the first one is from the data gathered and the other two are the confidence interval. I now want to shadow the area between the confidencial interval (best in grey) but until now i failed miserably. Can someoene help me?

figure
subplot(3,1,1)
plot(average_a_A_plot_cont1,'DisplayName','average_a_A_plot_cont1');  %curve from the data
hold on
plot(ci_durch1(:,:));                                                  %curves from the confidence interval
hold off
title('limited memory; memory length =5, umwsd 5, 25, 45 ');
ylim([0 1])
xlabel('Timesteps') 
ylabel('Performance') 
grid on
pbaspect([1 1 1])

I do not have your data, so I created my own.

You may have to change it slightly to fit your intended application.

Try this:

x = (1:20).';                                               % Create Independent Variable Vector
y = 2 + 3*x + randn(size(x))*10;                            % Create Dependent Variable Vector

mdl = fitlm(x, y);                                          % Estimate Parameters
[ypred,ci] = predict(mdl,x);                                % Calculate Regression & Confidence Intervals

figure
plot(x, y, 'p')
hold on
patch([x; flipud(x)], [ci(:,1); flipud(ci(:,2))], [1 1 1]*0.8, 'EdgeColor','none', 'FaceAlpha',0.2)
plot(x, ypred, '-r')
hold off
grid

The patch call creates the shaded confidence intervals.
