My system of equations have both linear and non-linear equations but not quadratic or cubic or equations having variable degree more than one. example :
x + y = 3 (linear), y + z = 4 (linear), x * z = 6 (non-linear), x / y = 3 (non-linear), y * z / x = 2 (non-linear)
There can be hundreds of equation in these system. There is no quadratic or cubic equation.
I want to know which algorithm is best for solving these system of equations and which language is better C or Matlab .
