calculate differential equation in MATLAB

Hi, I want to calculate this differential equation. please help me.

Could you please show your attempts and then let the community know your specific questions in solving this exercise?

De facto, you can start working with MATLAB's built in symbolic ODE solver, such as dsolve(). If you have ICs, other numerical solvers, such as ode23, ode45, ode15s, ode113, etc.

I started with this

z = float('double')

syms y(omega) y2(omega2) n(omega) n2(omega2);

ode1 = diff(y,z)-(i/n)*m*y == 0;

ode2 = diff(y,z)-(i/n2)*m^2 == 0;

Solv(x) = dsolve(ode1 , ode2)

but I dont know how to define beta and this code gives an error to me.
