`mvMatrixElementScale`

mvMatrixElementScale(RealPos[][] x, RealPos lambda, Bool tune, Natural row, Natural col, RealPos weight, Probability tuneTarget)

x :	RealPos[][] (<stochastic> pass by reference)
	The variable on which this move operates.
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
row :	Natural (pass by value)
	Confine the move to this row; omit to use every element.
	Default : NULL
col :	Natural (pass by value)
	Confine the move to this column; omit to use every element.
	Default : NULL
weight :	RealPos (pass by value)
	The weight determines the relative frequency with which this move will be attempted. For details, see the description of the 'moveschedule' parameter on the documentation page for 'mcmc()'.
	Default : 1
tuneTarget :	Probability (pass by value)
	The acceptance probability targeted by auto-tuning.
	Default : 0.44
