break up filtered EMG data into epochs

hello,

I have a filtered EMG signal that i have to break up into 1.5s epochs so i could apply a periodogram function. But i am not sure how to break it up with a simple command.

Try something like this

t = linspace(0, 10, 1000);
eeg_signal = rand(size(t)); % eeg-signal

grps = ceil((t+eps).'/1.5);
eeg_split = splitapply(@(x,y) {[x, y]}, t(:), eeg_signal(:), grps);

How can i plot it?

See plot() function.
