Defining boundary condition at infinite x for ODE

Hello,

I am solving ODE, and how can I write Matlab command to express the termninal x value as infinite?

hi Daniyar, You mean setting Tspan as Inf ? if yes then :

i do not think its logic to make the bound as Inf , but instead make a large value , ok try this :

 >>f=@(y,x) sin(x+y).*exp(-x.^2-y.^2)
 >>[t,y]=ode15s(f,[1 2],[0 Inf])
 >>[t,y]=ode15s(f,[1 2],[0 1e+9])

does this helps ?
