Hi!
I am trying to estimate 13 unknown parameters involved in 4 ordinary differential equations (ODEs) by fitting it to experimental data. There are six variables (4 dependent variables and 2 independent variables). Eight set of data points are available. Equations are as follows.
- dYB/dt = -(r1) - (r2)
- dYH2/dt = (8*r1) + (12*r2) + (r3) - (r4)
- dYCO/dt = (4*r1) - (r3) + (r4)
- dYCO2/dt = (4*r2) + (r3) - (r4)
Where r1 = k10*e^(-E1/(RT))*(PB^a), r2 = k20*e^(-E2/(RT))*(PB^b), r3 = k30*e^(-E3/(RT))*(PCO^c), r4 = k40*e^(-E4/(RT))*(PCO2^d)*(PH2^e).
I tried to estimate parameters using lsqcurvefit and ode15s, but there are errors which I am not able to rectify.
Thank you in advance.

V has 4 elements, namely [YH, YH2,YCO, YCO2].
What are you trying to do when you refer to V(5,:) ?
