Constructor & Destructor Documentation

Sampler() [1/2]

gtsam::Sampler::Sampler ( const noiseModel::Diagonal::shared_ptr &  model, uint_fast64_t  seed = 42u  )

explicit

Create a sampler for the distribution specified by a diagonal NoiseModel with a manually specified seed

NOTE: do not use zero as a seed, it will break the generator

Definition at line 23 of file Sampler.cpp.

Sampler() [2/2]

gtsam::Sampler::Sampler ( const Vector &  sigmas, uint_fast64_t  seed = 42u  )

explicit

Create a sampler for a distribution specified by a vector of sigmas directly

NOTE: do not use zero as a seed, it will break the generator

Definition at line 32 of file Sampler.cpp.
