Constructor & Destructor Documentation

§ Rotation2() [1/3]

KDL::Rotation2::Rotation2 ( )
inline

c,s represent cos(angle), sin(angle), this also represents first col.

of rot matrix from outside, this class behaves as if it would store the complete 2x2 matrix. Default constructor does NOT initialise to Zero().

§ Rotation2() [2/3]

§ Rotation2() [3/3]

KDL::Rotation2::Rotation2 ( double  ca,
double  sa 
)
inline

§ Rot()

IMETHOD Rotation2 Rotation2::Rot ( double  angle)

IMETHOD void Rotation2::SetIdentity ( )
inline

§ SetInverse()

§ Equal

bool Equal ( const Rotation2 a,
const Rotation2 b,
double  eps = epsilon 
)
friend

do not use operator == because the definition of Equal(.,.) is slightly different.

It compares whether the 2 arguments are equal in an eps-interval

§ operator*

Rotation2 operator* ( const Rotation2 lhs,
const Rotation2 rhs 
)
friend
