solve() [1/2]

Solution siderust::lambert::solve ( const double(&)  r1_km[3], const double(&)  r2_km[3], double  tof_s, double  mu_km3_s2, Branch  branch = Branch::Prograde  )

inline

Solve Lambert's single-revolution two-point boundary-value problem.

Parameters

r1_km	Departure position [x, y, z] in km (3 elements).
r2_km	Arrival position [x, y, z] in km (3 elements).
tof_s	Time of flight in seconds.
mu_km3_s2	Gravitational parameter of the central body, km³·s⁻².
branch	Prograde (default) or retrograde transfer.

Returns

Solution Departure/arrival velocities and solver diagnostics.

Exceptions

siderust::InvalidArgumentError

if the solver fails to converge or the input geometry is degenerate.
