mvMultipleElementVectorScale(RealPos[] x, Natural numToMove, RealPos lambda, Bool tune, RealPos weight, Probability tuneTarget)


x : RealPos[] (<deterministic> pass by reference)
The variable on which the move operates.
numToMove : Natural (pass by value)
The number of vector elements changed per move.
Default : 1
lambda : RealPos (pass by value)
The scaling factor (strength) of the proposal.
Default : 1
tune : Bool (pass by value)
Should we tune the scaling factor during burnin?
Default : TRUE
weight : RealPos (pass by value)
The weight how often on average this move will be used per iteration.
Default : 1
tuneTarget : Probability (pass by value)
The acceptance probability targeted by auto-tuning.
Default : 0.44
