I have 2 value in loop show that
T0 = [1035 1200];%K
for i = 1:length(T0)
L0 = [0 5e-6] ;%m
yi0 = [1 0 0] ;%molfrac(ya0 yb0 yc0)
P0 = 162.*yi0 ;%kPa
v0 = 2.037e-3 ;%m3/s (volumetric flowrate)
R = 8.314e-3 ;%(kPa*m3)/(kmol*K)
Fi0 = (P0.*v0)./(R.*T0(i)) ;%[Fa Fb Fc][mol/s mol/s mol/s]
Var0 = [Fi0 T0(i)] ;
[L ,Vary] = ode45(@Try_loop,L0,Var0) ;
end
So I want to save every value i in different file in excel for example when i = 1035 and code run to end then save result calculate of 1035 in excel. I don't know how to save it not to overlap on the same value.

Do you want 1035 different files? Do you want 1035 different sheets in the same file? Do you want (1035 * 3) columns in the same sheet, with the columns being different length? Do you want a single time column followed 1035 pairs of columns the same length as each other?

Hi Jidapa, type in your matlab terminal
doc xlswrite
This will give you lots of information about how to do it.
As an example, to write data given by the variable "A" in sheet "2" starting in cell "E1", you just use the following code:
filename = 'testdata.xlsx';
A = {'Time','Temperature'; 12,98; 13,99; 14,97};
sheet = 2;
xlRange = 'E1';
xlswrite(filename,A,sheet,xlRange)
In your case, "sheet = i" should work, simply adapt the rest of the example to your needs ;)

These days we would recommend writetable() or writematrix(), with the 'Sheet' parameter.
