I have this code, where 'data' changes its size with every loop and has to be divided into four equal segments. This division has to be stored in variable 'epoch'. storing it in cell variable isn't an option. How can I store differen lengths of data?

data = y; seg = y/4; signal = data(1,:); for e = 1:4 epoch (e,:) = signal(1+(e-1)*seg:e*seg); end

I have a data matrix each for 100 persons.Initially I was dividing columns into four segments (see code below). Now this data matrix vary, instead of 10000, the columns have different lengths. How can i divide them into 4 segments?

data_10_col = data(:,[1:10000]); for e = 1:4 epoch(e,:) = data_10_col(1+(e-1)*2500:e*2500); end
