AlgebraicSymMatrix33 theCartesianError

Detailed Description

template<class T, class ErrorWeightType>
class GlobalErrorBase< T, ErrorWeightType >

Templated class representing a symmetric 3*3 matrix describing, according to the ErrorWeightType tag, a (cartesian) covariance matrix or the weight matrix (the inverse of the covariance matrix).

The typedefs should be used in the code.

Definition at line 26 of file GlobalErrorBase.h.

template<class T, class ErrorWeightType>
GlobalErrorBase< T, ErrorWeightType >::GlobalErrorBase ( ) [inline]

Default constructor, creating a null 3*3 matrix (all values are 0)
