thank you mr madhan ravi for your help but its plots to me just for the last value of lambda_3=0.6 , why ?

[madhan ravi]

I see all three except with an exception in figure(1) perhaps they overlie on top of each other so it’s not tangible.

[diadalina]

yes,it is my matlab problem, i want to ask you another question if it is possible, if i want to change two parametres in the same time and plot the figures in the same maner for example lambda3=0.1,sigma3=0.1, lambda3=0.4,sigma3=0.4,lambda3=0.6,sigma3=0.6,, how can i do it ?

[madhan ravi]

It goes the same way

for k = 1:3
  ode45(@(t,Y) funsys(t,Y,lambda3(k),sigma3(k),...)
.... blah blah blah

okey , thank you very much, i will try it .
