Question

Units in the rkfixed function

We can use units in Mathcad Prime by the solving ODE. It is very good! But I see one error:

It is very strange:

rkfixed - 1 error

Rkadapt - 2 errors

Radau - no error

(1+2+0) / 3 = 1 Error!

And then I was happy that the unit can now be used by the solving differential equations

One calms me - in Maple we have same disorder by using units in the solving differential equations
