Document of fsolve states :
options is a structure specifying additional parameters which control the
algorithm.
Currently, fsolve recognizes these options:
"AutoScaling", "ComplexEqn", "FinDiffType", "FunValCheck", "Jacobian",
"MaxFunEvals", "MaxIter", "OutputFcn", "TolFun", "TolX", "TypicalX", and
"Updating".
Did you specify "ComplexEqn" option?
