Attach the data and code.

This line:

TimeM = [AA(:,1) BB(:,1) CC(:,1) DD(:,1)] ; 

will throw error. Note that BB, CC and DD are of size 20x2 and AA(:,1) is of size 24x2. So you cannot join/ concatenate four columns of size 24x1 and 20x1. Obviously, it will trhow error. So what you can do is:

data = [AA ; BB; CC; DD] ; 
TimeM = data(:,1) ;
VoltM = data(:,2) ; 
plot(TimeM,VoltM)

is there a way to get join them in seperate column? i dont wan to get a column of 84x1

Yes, you can. You can interpolate AA from 24x2 to 20x2 or interpolate BB, CC, DD from 20x2 to 24x2. I have shown below converting AA from 24x2 to 20x2. You need to read about interp1.

x = AA(:,1) ;
y = AA(:,2) ;
xi = linspace(min(x),max(x),20)' ;
yi = interp1(x,y,xi) ; 
AA = xi yi] ;
TimeM = [AA(:,1) BB(:,1) CC(:,1) DD(:,1)] ;
