Hi there,
Don't know if the subject is reasonable. In the model I am trying to
solve have a function like:
Pi = a * dPhi/dt + b * dAlpha/dt + c
dPhi/dt = ....
dAlpha/dt = ....
I don't know how to make the model equation for the first equation.
I try to use deSolve package.
Any suggestions? Thanks in advance.
Best,
Jinsong
