I plot a bar figure using grouped style. the m-code that does so is:
figure; bar([cov_filt3(1:4)' cov_filt4(1:4)'], 'group');
now I'd like to changed the color of the bars individually. How does it

I observe strange behavior when requesting subscript-style

the problem when the input to FIND is 3D (when input is a
matrix there's no problem; I haven't checked to see what

I heard that the matlab way of object oriented programming is a little

I'm trying to generate triggers at the start of specific times so I've
created a timer object. However, these specific times are created by
