*
|
|
* Data structure to store the results of one simulation
|
|
* of the SIR (susceptible-infected-recovered) model on a graph.
|
|
*
|
|
* It has the following members. They are all (real or integer)
|
|
* vectors, and they are of the same length.
|
|
*
|
|
* \member times A vector, the times of the events are stored here.
|
|
* \member no_s An integer vector, the number of susceptibles in
|
|
* each time step is stored here.
|
|
* \member no_i An integer vector, the number of infected individuals
|
|
* at each time step, is stored here.
|
|
* \member no_r An integer vector, the number of recovered individuals
|
|
* is stored here at each time step.
