Part (e) please! Plot the vector fields in MATLAB ifpossible.For comparing to part (b) and (c):Part (b):d(I/dt)=0 ; d(R/dt)=0?SI-?I-wI = 0?I-wI =0Fixed points for first equation: I=0 ; (?+w 2. Consider the spread of an infectious disease modeled using an SIR model which incorporates birth and death. For simplicity, we will assume that birth and death occur at the same rate in all compart 1 answer
