Index exceeds matrix dimensions (Monod kinetics and curve fitting)

Hi, I'm trying to fit dS/dt = -v1*ktot1*SSA1*S*(1-Kad1*S/(1+Kad*S)) on to experimental data (deg25deg.mat). Yet I get this error message:

" Index exceeds matrix dimensions.

Error in dissolutionKinetics/NSdeg25deg (line 10) xdot(1)= -1.*B(1).*B(2).*B(4).*x(1).*(1-((B(3).*x(1))/(1+(B(3).*x(1)))));

Error in odearguments (line 90) f0 = feval(ode,t0,y0,args{:}); % ODE15I sets args{1} to yp0.

Error in ode45 (line 115) odearguments(FcnHandlesUsed, solver_name, ode, tspan, y0, options, varargin);

Caused by: Failure in initial objective function evaluation. LSQCURVEFIT cannot continue". I don't know what to change on line 10. Please help. Please find the *.m files on the attachment.

Have you tried using the debugger and looking at the size of your variables?

I've tried that, it only points out where the error is, but I don't know what to do to rectify the error.

[José-Luis]

It does more than pointing out where the error is.

Place a breakpoint where the error occurs and look at the size of the offending variables where the error occurs.

I am currently trying different things, as I read from previous answers to previous similar question. The current error is "Not enough input arguments". I will keep on trying until I win.
