Is this code correct for split an EMG signal into 10 equal part?

total number of samples are 1000 should I write like this?

part1 = EMG(1:100);
part2 = EMG(100:200);
part3 = EMG(200:300);
part4 = EMG(300:400);
... 
until part10 ?
is any shorter code to write it?

No, not if you want 10 separate, individually named variables. At least none that I would recommend.

By the way, the indexes should start with 101, 201, 301, etc., NOT 100, 200, 300, etc.

yes that's right, thnak you

Here's the FAQ to the NOT recommended way http://matlab.wikia.com/wiki/FAQ#How_can_I_create_variables_A1.2C_A2.2C....2CA10_in_a_loop.3F. Again, don't do it that way - the FAQ explains why not.

I write it with a for loop but i have some errors , wolud you help me with this?

% my emg signal has 10000 sample , i wrote it 1000 as a mistake before
  for i = 0:9
        EMG(i+1) = EMG((i * 1000) + 1:(i + 1) * 1000);
        m_a(i+1) = mean(abs(EMG(i + 1)));
  end

You can't stuff 1000 elements into one element. I recommend you just use the 10 different variables, or just use indexes when you need to extract a portion, and leave the array as it is.

The other option is to use a cell array but I don't recommend that. You'd have to use a different name if you did, like caEMG instead of EMG.
