Hello,
I would like to display the mean values from various measurements and of course the deviations using "errorbar".
Assuming the following series of measurements are given:
Test_01=[1 2 3 4 5 6]
Test_02=[1.5 2.5 3.5 4.5 5.5 6.5]
Test_03=[0.5 1.5 2.5 3.5 4.5 5.5]
x=[1 2 3 4 5 6]
Can a plot with errorbar be generated directly from this or does the mean value and deviations have to be calculated manually?

I would do something like this:
Test_01=[1 2 3 4 5 6];
Test_02=[1.5 2.5 3.5 4.5 5.5 6.5];
Test_03=[0.5 1.5 2.5 3.5 4.5 5.5];
x=[1 2 3 4 5 6];
Test_All = cat(1, Test_01, Test_02, Test_03);
TestMean = mean(Test_All);
TestStdv = std(Test_All);
figure
errorbar(x, TestMean, TestStdv)
grid
xlim(xlim+[-1 1])
The xlim call simply moves the first and last points away from the axis edges, and is optional.

You should calculate meaningful error estimates yourself (SD, SEM, etc), and plot it with errorbar.
doc errorbar
