MATLAB: Missing coefficients in symbolic expressions with coeffs

coefficientscoeffsexpressionssymsymbolic

Ok, I have been trying to use coeffs here is what I am currently have a problem with, although I have 5 symbolic variables, not all show up in every equation so when I try and gather coeffients I would like to be able to catch even the 0 values. heres what I have so far.
clc
clear 
m= [2 -3 ; 3 -2];
q = [ -1 -1]';
xv = sym('x1');
lm = length(m);
yv = sym(zeros(1, lm))';
zv = sym(zeros(1, lm))';
for k=1:lm
yv(k) = sym(sprintf('x%d', k+1));
zv(k) = sym(sprintf('x%d', k+lm+1));
end
A = [-(m*yv+xv*q);m*yv+xv*q-zv; yv-zv;zv-yv];
Aineq=zeros;
temp = zeros;
for i=1:length(A)
  temp=coeffs(A(i,:))
  for j=1:length(temp)
      Aineq(i,j)=temp(j)
  end
end
Aineq
the last nested for was my attempt to gather the coefficients. I but I cannot place them in the right way this way. Any suggestions? I have looked at ineval and feval but I do not see the how to use these tools
Oh this is what my output looks like A =
   -2*x2+3*x3+x1
   -3*x2+2*x3+x1
 2*x2-3*x3-x1-x4
 3*x2-2*x3-x1-x5
           x2-x4
           x3-x5
           x4-x2
           x5-x3  
  Aineq =
     1    -2     3     0
     1    -3     2     0
    -1     2    -3    -1
    -1     3    -2    -1
     1    -1     0     0
     1    -1     0     0
    -1     1     0     0
    -1     1     0     0  
So this is where I am stuck at this point.

This is what I was able to do thanks for all the help. I will post the final solution to the larger problem if anyone wants to see it.
    clc
    clear 
    m= [2 -3 ; 3 -2];
    q = [ -1 -1 ]';
    xv = sym('x1');
    lm = length(m);
    yv = sym(zeros(1, lm))';
    zv = sym(zeros(1, lm))';
    for k=1:lm
    yv(k) = sym(sprintf('x%d', k+1));
    zv(k) = sym(sprintf('x%d', k+lm+1));
    end
    A = [m*yv+xv*q+zv;-(m*yv+xv*q); yv-zv;zv-yv];
    for i=1:length(A)
        A(i,:)=sort(A(i,:));
    end
    xx = cat(1,xv ,yv,zv);
    Aineq = zeros(numel(A),numel(xx));
    for j=1:length(A)
        for i=1:length(xx)
        y=xx(i);
        [c,t]=coeffs(A(j),y);
            if (length(t)<2)
            else
                insert=c(2);
                Aineq(j,i)=insert;
            end
        end
    end
    Aineq;
    bineq=zeros(length(Aineq),1);
    for temp=1:(length(zv))
            bineq(temp,1)=1;
    end
