vsmc::NormalMVProposal< RealType, Dim >::NormalMVProposal ( const result_type *  chol = nullptr, const result_type *  a = nullptr, const result_type *  b = nullptr  )

inlineexplicit

Only usable when Dim != Dynamic

Parameters

chol	The lower triangular elements of the Cholesky decomposition of the covaraince matrix, packed row by row. If it is a nullpointer, then the covariance is the identicy matrix \(I\)
a	The lower bound of the support of the target distribuiton. It is assumed that the support is \(\prod_{p=1}^d E_p \subset \mathbb{R}^d\) where \(E_p \subset \mathbb{R}\).
b	The upper bound of the support of the target distribution.

If the geometry of the support is more complex than above, then one may find a superset of the support that takes the required form, and reject proposals that lay outside the support manually.
