Hi there,
I would like to ask you how to solve a system of nonlinear equations while using symbolic variables.
I have two equations that I need to solve:
eqT = 10*lamT^13*lamZ^13 – 10/lamT^13 – 10*lamT^2*lamZ
eqZ = 10*lamT^13*lamZ^13 – 10/lamZ^13 – 5*lamT^2*lamZ
where lamT and lamZ are symbolic.
I was trying to search for it and most times I have found to use matlabFunction and fsolve. But it doesn’t work for me. Probably I understand it wrong or maybe I am doing another mistake.
fun = matlabFunction(eqT, eqZ)
eqsol = fsolve(fun,[1 1])
Can you please help me and explain me what I am doing wrong.
Thank you very much

P.S.: it is not possible not to use symbolic variables. They are used for some derivations before. Also it is not possible to rewrite the equations manually because they are to be solved many times in for cycle with different constants.Hi there,
