Would like to create a 2x3 matrix using for loop

pnh3=.046;      %%torr
po2=.068;       %%torr
R1=1.987 ;       %%cal/gmol*K
R=62.364;       %%torr L/gmol K
vo=100/3600;    %%L/s
T=zeros(3,1);
T(1)=473;
T(2)=673;
T(3)=800;
z=Ljallo_f1_q1(T,R1,pnh3,po2); 
fio=Ljallo_f2_q1(T,R,vo,pnh3,po2);

function iFlows=Ljallo_f2_q1(T,R,vo,pnh3,po2)
cnh3=zeros(3,1);
finh3o=zeros(3,1);

co2=zeros(3,2);
fio2o=zeros(3,2);

iFlows=zeros(3,2);

for i=1:3
cnh3(i,1)=pnh3/(R.*T(i));
finh3o(i,1)=cnh3(i,1).*vo;
iFlows=finh3o(i,1);

co2(i,2)=po2/(R.*T(i));
fio2o(i,2)=co2(i,2).*vo;    
iFlows=fio2o(i,2);

end

>> Ljallo_s_q1
>> fio

fio =

   3.7860e-08

>> 

I want to create a 2x3 matrix for 'fio'. however, when I call it I get one anwser.

This line has an error,

iFlows=fio2o(i,2);

The right hand side fio2o(i,2) is a scalar, but there is no indexing on the left hand side to tell where in iFlows it should be assigned to. So, the whole array iFlows simply gets overwritten.

Thank you! Got it!
