Hi,
I have large dataset in structure arrays. Hundred of subctructures (1x100), it looks like
data = 1x100 struct array with fields:
timestamp (not interesting)
stimIndex (not interesting)
stim (not interesting)
signal (column of samples - important)
I would like to store just with signal (data(1,1).signal, data(1,2).signal....data(1,100).signal). I don´t know how to make the loop, which will store just the signal data and do it hundreds of times. 100 dataset - 100 file. I hope it is quite clear.
Many thanks for tips

That is already stored but if you want it to store in another non struct variable, you need not use a loop. follow this:
Signal = {data.signal} % will result in cell array

According to your tip, I have matrix 1x100 and each element contains my signal. That is good but now I don´t know how to work with that. For example I would like to do sum of this signals (like averaging).
I thought the FOR loop will be usefull. I wanted make folder with 100 signal files and then work with signals separately.

That results in a cell array not a matrix. You can access individual signals using:
mat = Signal{1}; % Access 1st signal
Go through the attached link to know more about cell arrays, like how to access individual element or how to operate on them http://www.mathworks.in/help/matlab/cell-arrays.html
