Solve of ODE with AdamsBDF don't work Mathcad Prime 4.0

[fgörlich]

Hi,

I' new in Mathcad Prime. i need it to solve ODE systems.

I try to solve the Example of the GDG solver with the AdamsBDF methode.

My problem is the vector function. I don't find any solution. Same thing with rkfixed. I hope anyone can help me.

I can't open your file but it looks to me that you used literal indices (with ctrl+-) instead of vector/matrix indices (with [).
