Not sure what you mean by "_expression_". Implementation-wise,

f(...) means call the user's odefun with the arguments in ().

So that is what the code does with the last two equations of page 6.

Similarly, g(...) means call the user's bcfun.

The last equation on page 6 gives f_{i - 1/2} in terms of f evaluated at x_{i
- 1} + h/2 .

Does this not mean that we need an _expression_ for f evaluated at this mid
way point between mesh-values?
