please excuse me if this is an extremely simple question as i am new to matlab.
My code goes as follows:
[x, fs] = audioread('stereo.wav');
LeftChan = x(:,1); %extracting the left channel
RightChan = x(:,2);%extracting the right channel
LengthLeft = length(LeftChan);
%new another L here which adds the zero's to the end of L
ZeroPad = zeros(1,558);
NewLengthLeft = LengthLeft + ZeroPad;
n = 2048; %frame size
N = NewLengthLeft/n; %total number of frames
%Frames for Left Channel
for i = 1 : N
inputBuff = LeftChan((i - 1)*n+1 : i*n); %processing buffer
e = 0;
for j = 1 : n
e = e + inputBuff(j) * inputBuff(j);
end
end
i would like to add the zeros onto the end of the signal, however at the moment it doesnt seem to want to work.
Thanks in advance

k = rand(100,1) ; % a random signal/ row vector
z = zeros(10,1) ; % a zero row vector
iwant = [k ; z] ;
