dual-zero clj/s

(dual-zero z)

F->CT clj/s

(F->CT F)

A transformation of configuration coordinates F to a procedure implementing a transformation of phase-space coordinates (p. 320)

H-central clj/s

(H-central m V)

H-central-polar clj/s

(H-central-polar m V)

H-rectangular clj/s

(H-rectangular m V)

Hamilton-equations clj/s

(Hamilton-equations Hamiltonian)

Hamiltonian clj/s

(Hamiltonian & n)

Return SICM-style function signature for a Hamiltonian with n degrees of freedom (or 1 if n is not given). Useful for constructing Hamiltonian literal functions.

Hamiltonian->state-derivative clj/s

(Hamiltonian->state-derivative Hamiltonian)

iterated-map clj/s

(iterated-map f n)

f is a function of (x y continue fail), which calls continue with the values of x' y' that follow x y in the mapping. Returns a map of the same shape that iterates the iterated map n times before invoking the continuation, or invokes the fail continuation if the inner map fails.

Lagrangian->Hamiltonian clj/s

Legendre-transform clj/s

Lie-transform clj/s

(Lie-transform H t)

p. 428

momentum clj/s

(momentum H-state)

See coordinate: this returns the momentum element of a Hammilton state tuple (by convention, the element at index 2).
