This code will retrieve recent state-level data from Wikipedia and attempts to fit it to a SIR model using structure created by Milan Batista.(https://www.mathworks.com/matlabcentral/fileexchange/74658-fitviruscovid19?s_tid=prof_contriblnk). The model is data-driven, so its forecast is as good as data are. Also, it is assumed that the model is a reasonable description of the one-stage epidemic.

Results are saved in structure res (see function fiVirusCV19_state header). Optionally the results may be printed by:

fitVirusCV19_state('Massachusetts','plt','on')

The plot may be enabled or disabled via (default is on):
fitVirusCV19_state('Massachusetts','prn','on')

To plot the growth rate on the figure use (def value is 2)
fitVirusCV19_state('Massachusetts','nsp',3)
