Okay you got me, what is a semi discretization?
]]>Do you have some initial conditions for post#1. If I have initial conditions I might be able to.
]]>I am already stuck on how he derived:
]]>I have the 1999 edition. My pahe 50 has a figure 2.12 on the top. Am I in the right spot?
]]>so please.. help me dude..
]]>I have that book, please tell me where in it are you exactly working! Maybe I can help out.
]]>my exercise is to analyze the fixed point stability from discrete time epidemic model.but the model on that book can't be anlyzed, so i think to change from the continuous model to discrete model.. i'm so thankful..
]]>I am a little confused here. As far as I know you can convert a DE ( continuous ) into a Recurrence ( discrete ), you don't convert the constants. I don't understand what you are trying to accomplish. Can you give more? What textbook or webpage are you studying from?
]]>ex :
dS/dt = (alpha)*n- (alpha)*S - (beta)*S*I
dI/dt = (beta)*S*I- (gamma)*I
dR/dt = (gamma)*I
become
S = ??
I = ??
R =??
thank you very much...
