How can I do a loop to extract vectors from a matrix?

Hello, I am working with EEG signals and I have a 21*2560 matrix. I want to split it into 21 channels each one with nc*2500 taking into account that nc takes values from 1 to 21. Also store every channel in a new variable.

matriz= AD1; %AD1(21*2560)

[i,j]=size(matrix); for h=1:i c=M(h,:); % I want to create new vectors each time, if I do this only the last one is stored end

The reason only the last one is stored at the end of the for loop is that 'c' is being overwritten each time the loop iterates.

Consider storing the new vectors created inside the for loop in a cell array. For example:

for h=1:i
   c{h} = a(h,:)
end

c{1}, c{2} ...c{21} each contain a 1 x 2560 matrix.
