Model fitting for real data using matlab lsqcurve

I have a program which I need an assistant.

I have a system of 5-ODe model and my excel file has multiple sheets and each sheet has multiple columns.

Sheet1 has confirmed case from each state in Nigeria and the last column is the total confirmed

Sheet2 has Recovered case from each state in Nigeria and the last column is the total Recovered

Here is the thing I need to do

1. Model fitting to real data (MATLAB Lsqcurve) for all parameters then for infected parameter

2. Forecasting with the parameters (to get the peak time of infected and time to end infection. The file above contains the model. There's no data for Susceptible and exposed. Please I will appreciate if you help me

Thanks
