Jim, I don't see where the input "t" is being used.

It that an error, or intentional?

In any event, you should be able to skip creating of function file for  
mmjam entirely, by defining the function as ...

        dqadt = @(t,y) [qin - vmax/(1+km/(y/sz))]

You can do that in mmjam0.m. This also allows  you to delete the  
"global" variables. I've attached a modification of your example that  
works for me (I'm running Octave 3.0.3).
