Hello, I am trying to solve the following ODE:
syms mu(z) theta u_o Kx Ky h z rho wu_x = cos(theta)*u_o*(cos(Kx*z)+tan(Kx*h)*sin(Kx*z));du_x = diff(u_x,z);eqn1 = diff(mu(z)*du_x,z) == -rho*w^2*u_x;dsolve(eqn1)
However I get the following error message:
Warning: Unknown functions not appearing in the system are ignored. > In symengine In mupadengine/evalin (line 102) In mupadengine/feval (line 161) In dsolve>mupadDsolve (line 336) In dsolve (line 194) In main (line 68) Error using mupadengine/feval (line 166)The number of arguments is incorrect.Error in dsolve>mupadDsolve (line 336)T = feval(symengine,'symobj::dsolve',sys,x,options);Error in dsolve (line 194)sol = mupadDsolve(args, options);Error in main (line 68)dsolve(eqn1)
I would understand a message saying it didn't find the explicit solution, but here I don't know what to make of it.
Does anyone know where this is coming from and what i could try to solve this ODE?
Thank you,
Nicolas
