In the paper attached, titled "Stability and bifurcation analysis of an SIR epidemic model with logistic growth and saturated treatment" . I ask about the way to do the figures related with bifurcations and vectors field.
Hi Abdulaziz,
The bifurcation diagram is a qualitative tool use to determine transitions is a dynamical system. They are obtained by plotting the extrema of the system in terms of a chosen bifurcation parameter. Regarding the vector field, excellent exemples are provided in matlab help. You can just adapt your system accordingly.
Best regards
The MATLAB function "quiver" can be used to plot vector fields. MATLAB program to plot the bifurcation diagram of a logistic map are available in the MATHWORKS website. You can modify them for the map which you are dealing with.
You can use dfield and pplane.
