How to extend a vector continuously in a loop

I have to construct a vector for my initial conditions to solve my ode system. Im modelling CSTR in series, and for each reactor i need initial conditions for 10 differential equations, which is defined as

ini_vector=[par.nN2_in par.nH2_in 0 0 0.01 0 0 0 0 0.999];

Initially i have only modeled 8 CSTR in series, so i have defined my vector of initial conditions as:

initial=[ini_vector ini_vector ini_vector ini_vector ini_vector ini_vector ini_vector ini_vector];

Is there a more simple way to make this vector initial?

I have tried to set up a loop to make the vector for 1000 CSTR

ini=[];

for k=1:N_CSTR

ini_vector=[par.nN2_in par.nH2_in 0 0 0.01 0 0 0 0 0.999];

initial = [ini ini_vector];

end

but my code is not working.. I've searched for simular examples but have not found any that seem to enlighten me on how to make this work. I would be grateful if someone could suggest a way to make this work..

ini_vector=[par.nN2_in par.nH2_in 0 0 0.01 0 0 0 0 0.999];
Initial = repmat(ini_vector,1,8)
