### D.13.1 `minpack` calling conventions

The `minpack` library solves a similar problem to that of the `kinsol` library (`kinsol`), and the two libraries have identical calling conventions at the level of the virtual code interface.

The `hybrd` and `lmdif` functions take input arguments of the form `(f,(i,o))`, whereas `hybrj`, `lmder`, and `lmstr` take arguments of the form `((f,j),(i,o))`. The interpretations of these parameters are explained in `kinsol` input parameters.

For the `lmstr` function, the Jacobian function j takes an argument `(m,v)` and returns only the m-th row of the Jacobian matrix. For `lmder` and `hybrj`, the Jacobian function takes only an input vector v and returns the whole matrix. These specifications are also explained further in relation to the `kinsol` library.

The output from any minpack function is a vector v satisfying `f(v) = o` to the best possible tolerance if a solution is found. A range of tolerances over ten orders of magnitude is sampled starting from `1e-15`. If no solution is found, an empty list is returned.
