MATLAB: Would like to create a 2×3 matrix using for loop

for looploopmatrix

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 2×3 matrix for 'fio'. however, when I call it I get one anwser.

Best Answer

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.
