Hi!

I am trying to do nonlinear fitting for michaelis-menten enzyme kinetics using matlab and package enzkin. My paremeters are:

S = 3.6000 1.8000 0.9000 0.4500 0.2250 0.1125

v = 0.0047 0.0045 0.0037 0.0027 0.0018 0.0011

I run :

enzkin (S,v);

and I get error:

Undefined function 'fitoptions' for input arguments of type 'char'.

Error in enzkin (line 91) fo_ = fitoptions('method','NonlinearLeastSquares','Robust','On','Lower',[0 0]);

Does anyone know where is the problem?

Thanks, Martin
