Thank you for response. But it is not help me.
I have found answer in Leo Butler response:

But I don't know how I can solve following easy system in Maxima:
DSolve[{x^2 y''[x] + x y'[x] + (x^2 m^2 - k0^2) y[x] == a z'[x],
x^2 z''[x] + x z'[x] + (x^2 m^2 - k0^2) z[x] == b y'[x]}, {y, z}, x]
(I write this for Mathematica)
