I want to shade the area between these graphs
but this certainly does not do the trick:
fill([t t(end:-1:1)],[y1 y2(end:-1:1)],'y')
I also downloaded and tried "jblill"
but that did not seem to amend the outcome so far

Yes, there were answers below, one of which he accepted though both should work.

Try using fill() instead of area():
x = 1 : 300;
curve1 = log(x);
curve2 = 2*log(x);
plot(x, curve1, 'r', 'LineWidth', 2);
hold on;
plot(x, curve2, 'b', 'LineWidth', 2);
x2 = [x, fliplr(x)];
inBetween = [curve1, fliplr(curve2)];
fill(x2, inBetween, 'g');

@MadjeKoe simply don't call plot() and only call fill().

Try this:
x = linspace(0,10*pi);
y1 = sin(x);
y2 = cos(x);
figure(1)
plot(x, y1)
hold on
plot(x, y2)
patch([x fliplr(x)], [y1 fliplr(y2)], 'g')
hold off
Experiment with your data to get the result you want.

how can I avoid that?

This can be simplified using the function shade (in MATLAB File Exchange).
The syntax for the above problem would be:
shade(t,y1,t,y2,'FillType',[1 2;2 1]);
The FillType option specifies that the area between lines 1 and 2 should be filled, whether 1 is above 2 or the other way round.

It came to my minds one second after I posted. It works! Thanks.

I am using this last suggestion by Star Strider to plot error bar shading using patch, but in some cases I get in addition to the shading straight lines (see the third plot at the bottom in the attached figure) I have eliminated the points with NaNs. It seems ok in the other two cases (the upper plots in the same figure). What can be causing this?
