Member Enumeration Documentation

ECode

enum ECode

ECode is a error code enumerate.

Enumerator
kNoError	No error.
kNotFittedYet	Not fitted yet.
kOutOfRange	Specified track-id out of range.
kUnimplemented	Unprepared.
kBadTrackSize	Track count too small to perform fit.
kBadMatrixSize	Wrong correlation matrix size.
kBadCorrelationSize	Wrong correlation matrix size (internal error)
kBadInitialCHIsq	Bad initial chi-square (internal error)
kDivisionByZero	Division by zero (bad track property or internal error)
kCannotGetMatrixInverse	Cannot calculate matrix inverse (bad track property or internal error)
kCannotGetARCSIN	Cannot get arcsin (bad track property or internal error)
