Function Documentation

◆ angDistance()

template<class T >
T mrpt::math::angDistance ( T  from,
T  to 
)
inline

Computes the shortest angular increment (or distance) between two planar orientations, such that it is constrained to [-pi,pi] and is correct for any combination of angles (e.g.

near +-pi) Examples: angDistance(0,pi) -> +pi; angDistance(pi,0) -> -pi; angDistance(-3.1,3.1) -> -0.08; angDistance(3.1,-3.1) -> +0.08;

Note
Take care of not instancing this template for integer numbers, since it only works for float, double and long double.

void mrpt::math::extractColumnFromVectorOfVectors ( const size_t  colIndex,
const VECTOR_OF_VECTORS &  data,

inline

Extract a column from a vector of vectors, and store it in another vector.

  • Input data can be: std::vector<mrpt::math::CVectorDouble>, std::deque<std::list<double> >, std::list<CArrayDouble<5> >, etc. etc.
  • Output is the sequence: data[0][idx],data[1][idx],data[2][idx], etc..

◆ wrapToPiInPlace()

template<class T >
void mrpt::math::wrapToPiInPlace ( T &  a)
inline

Modifies the given angle to translate it into the ]-pi,pi] range.

Note
Take care of not instancing this template for integer numbers, since it only works for float, double and long double.
