[Eeglablist] Plotting standard error with std_plotcurve

[Arnaud Delorme]

Dear Pete,

I have tried the following code and it worked for me (it plots shaded areas).

cuealpha11 = rand(101,31);
cuealpha31 = rand(101,31);
cuealpha13 = rand(101,31);
cuetimes = linspace(-100, 600, 101);
std_plotcurve(cuetimes, {cuealpha11; cuealpha13; cuealpha31}, 'plotconditions', 'together', 'plotstderr', 'on', 'figure', 'on');

The configuration where it does not work is when cuealpha11; cuealpha13; cuealpha31 have different sizes.
Best,

Arno
