.. index:: rsamplers.imh.imh
.. _rsamplers_imh:

  rsamplers.imh is the constructor for the Independent Metropolis-Hastings algorithm
 
  The syntax is ::
 
  	obj = rsamplers.imh(target,x0,lb,ub)
  	obj = rsamplers.imh(target,x0,lb,ub,opts)
  	obj = rsamplers.imh(target,x0,lb,ub,opts,constraints)
 
  INPUTS :
 
    - \*target\* : objective to MAXIMIZE
    - \*x0\* : vector of initial conditions
    - \*lb\* : lower bound
    - \*ub\* : upper bound
    - \*opts\* : options for the class. These include the properties
      from the superclass rsamplers.rwmh as well as the specific
      properties of the imh algorithm that can be found in the
      properties list.
    - \*constraints\* (optional):  - Matrix (n_constraints x 2)
      where each row [a, b] enforces x(a) <= x(b)
 
  OUTPUT:
 
    - \*obj\* : object of class rsamplers.imh
 
  OWN PROPERTIES AND DEFAULT VALUES: None
 
  INHERITED PROPERTIES : properties from rsamplers.rwmh
