I have a non-linear equations system to solve in every loop step. I
have 4 equations with 8 variables. 4 of the variables are known and
calculated in each loop. I cannot find a way to pass the known
variables(which are different in each loop) into a BROYDEN or NEWTON
function to solve the system. If I put all 8 variables as input guess,
it won't calculate for me because there are 8 variables and 4
equations. I kind of stuck here.
