How to add zeros on the end of a signal.

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] ;
