Or if you want 4 1-D arrays:

part1 = eegSignal(1:2400);
part2 = eegSignal(2401:4800);
part3 = eegSignal(4801:7200);
part4 = eegSignal(7201:end);

Thanks for this but mat file structure is 65X9600 so i want to split it into 65*2400 ,65*2400 ,65*2400 and 65*2400 as part 1 part 2 part 3 and part4 ..

Kindly, help me out.

   x = randn(9600,1);
   len = 9600/4;
   x1 = reshape(x,len,4);

x1 is a matrix with 4 columns, each one is 9600/4 samples in length.
