Nested for and while loop

I want to generate matrix [a] and I want to the value [a] in while loop.
A=randi(2,2);
b=A*transpose(A);
c=chol(b,'lower');
p=normrnd(0,1,[1,10]);
q=p(p>0); z=q(1:2);
E1=c*transpose(z);
E=transpose (E1);
K=[67.3061 -8.1429;-8.1429 59.1633]
b=[0;4];
for i=1:length(E)
a(:,:,i)=E(i)*K
x(:,1)=[0;0];
n=20;
r(:,1)=b-a(:,:,i)*x
d(:,2)=r(:,1)
k=1;
while (k<n)
p=transpose(d(:,k+1))*a(:,:,i)*d(:,k+1)
q=(transpose(r(:,k))*r(:,k));
s(k+1)=q/p
x(:,k+1)=x(:,k)+s(k+1).*d(:,k+1)
u=a(:,:,i)*d(:,k+1)
v=s(k+1).*u
r(:,k+1)=r(:,k)-v
if r(:,k+1)<=0.001
break;
end
w=transpose(r(:,k+1))*r(:,k+1);
w1=transpose(r(:,k))*r(:,k);
c(:,k+1)=w/w1;
l=d(:,k+1)
g=(w/w1)*l
d(:,k+2)=r(:,k+1)+g
k=k+1;
end
end
