Detailed Description

Trajectory representation between two calculated points in 1d.

Uses either linear-linear, quadratic-linear or cubic-quadratic representation for location x and velocity v. Time is presented as a parametric, scaled variable K ranging from 0 to 1.


Constructor & Destructor Documentation

TrajectoryRep1D::TrajectoryRep1D ( ) [inline]

Default constructor for empty representation.

TrajectoryRep1D::TrajectoryRep1D ( double  dt,
double  x1,
double  v1,
double  x2,
double  v2,
trajectory_rep_e  force = TRAJ_EMPTY 
)

Constructor for representation of trajectory from (x1,v1) to (x2,v2) in time dt.

Can be forced to use a specified representation type by setting force. Defaults to TRAJ_EMPTY, which means that the highest numerically stable polynomial is automatically used.

TrajectoryRep1D::~TrajectoryRep1D ( ) [inline]

Destructor.


Member Function Documentation

void TrajectoryRep1D::construct ( double  dt,
double  x1,
double  v1,
double  x2,
double  v2,
trajectory_rep_e  force = TRAJ_EMPTY 
)

Construct representation of trajectory from (x1,v1) to (x2,v2) in time dt.

Can be forced to use a specified representation type by setting force. Defaults to TRAJ_EMPTY, which means that the highest numerically stable polynomial is automatically used.

void TrajectoryRep1D::coord ( double &  x,
double &  v,
double  K 
)

Calculate location x and velocity v at parametric time K.

void TrajectoryRep1D::debug_print ( void  ) const

Prints internal data to std::cout.

int TrajectoryRep1D::solve ( double  K[3],
double  x 
)

Solves for trajectory intersection with location.

Solves the trajectory intersection with location x. Saves the valid solutions to array K in increasing order and returns the number of solutions saved. The allowed limit for parametric time K is 0 < K =< 1, if include_start is false or 0 <= K =< 1, if include_start is true.
