Function definitions in a script must appear at the end of the file.
Move all statements after the "imene2022" function definition to before the first local function definition.

Functions defined in a script (such as imeme2022 in your script) must be positioned at the end of the script. The error message is clear enough. So, reposition these statements...
%constantes::
%temperature
T=17000
%constante k: recombinaison radiative
k1=2.36 *(1e-12)*(T/300)^(-0.29)*exp(17.60/T)
k2 =3.24 *(1e-12) *(T/300)^(-0.66)
k3=3.50 *(1e-12)*(T/300)^(-0.53)* exp(3.20/T)....
........
%initial
IC=10^19*ones(1,43)
[t,n]=ode45(@imene2021,[0 1e-3],IC)
plot(t,n)
end
above the function definition. BTW, the last line above is a dangling end statement and should be removed.
