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 [).
Yes, he did.
