fitting parameters for a system of differential equations
Tue, 03/24/2020 - 04:38 pm
I have defined a system of differential equations controlled by three parameters. it describes the time evolution of 3 species defined by 3 rate constants KK, KK and KK. The model is supposed to describe data that is presented in graph zero as lines and markers (the data describes the species labeled E0 and E2. E1, in this case, is just obtained by assuming E0 + E1 + E2 = 1). my goal here is to vary the KK parameters to get as close as possible to the data. ( I realize the fit will may not be great, and getting a good fit may require a more sophisticated model, just want to see how closely this model can fit) How can i do this with Igor? ihave attached the relevant pxp file which has all the data and the model in it.
