Hi... Can someone help and suggest a way how I can transform the answer to the solution which is a 4 set of 1x4 matrix to a 4x4 matrix.
clc;
T=253.2;
k12=0.1012;
m1=2.8149;
m2=2.0729;
sigma1=3.7169;
sigma2=2.7852;
E1=285.69;
E2=169.21;
k=1.38064852*10^-23;
d1=sigma1*(1-0.12*exp(-3*E1/T));
d2=sigma2*(1-0.12*exp(-3*E2/T));
X1=[0.1999 0.3997 0.5993 0.8002];
X2=[0.8001 0.6003 0.4007 0.1998]; %X2=1-X1
mbarliq=X1.*m1+X2.*m2;
etaassumedliq=[0.5 0.5 0.5 0.5];
etaliq=etaassumedliq;
rholiq=((6.*etaliq)./pi).*((X1.*m1.*d1.^3)+(X2.*m2.*d2^3)).^-1;
zetaliq=0;
for j=1:4
zetaliq=(pi/6).*rholiq.*(X1.*m1.*d1^(j-1)+X2.*m2.*d2^(j-1))
end
Below is the result from the above code:
However I would like it to be in the form of a 4x4 matrix such as below:
zetaliq=
x x x x
x x x x
x x x x
x x x x
Would appreciate the help. Thanks!

zetaliq=zeros(4);
for j=1:4
zetaliq(j,:)=(pi/6).*rholiq.*(X1.*m1.*d1^(j-1)+X2.*m2.*d2^(j-1)) ;
end
zetaliq
