inline |
Compute the current best estimate of all variables and return a full Values structure. If only a single variable is needed, it may be faster to call calculateEstimate(const KEY&).
|
inline |
Compute the current best estimate of a single variable. This is generally faster than calling the no-argument version of calculateEstimate if only specific variables are needed.

) |
Add new factors and variables to the smoother.
Add new measurements, and optionally new variables, to the smoother. This runs a full step of the ISAM2 algorithm, relinearizing and updating the solution as needed, according to the wildfire and relinearize thresholds.
newFactors | The new factors to be added to the smoother |
newTheta | Initialization points for new variables to be added to the smoother You must include here all new variables occuring in newFactors (which were not already in the smoother). There must not be any variables here that do not occur in newFactors, and additionally, variables that were already in the system must not be included here. |
