Thanks for the reply. Simulink does it "manually" - from the documentation:

"Use initial condition as initial and reset value for parameter:

Step 0: y(0) = x(0) = IC (clipped if necessary)
x(1) = y(0) = x(0) + K*T/2*u(0)

Step 1: y(1) = x(1) + T/2 * (u(1) + u(0))
x(2) = y(1)

Step n: y(n) = x(n) + T/2 * (u(n) + u(n-1))
x(n+1) = y(n)"

But I want to know if there's a shortcut. Please can you direct me to the right "type" of numerical integration - that wolfram link you gave provides wayyyy to many to choose from!
