IAS algorithm
=============

The Iterative Alternating Sequential (IAS) [Ref1]_ [Ref2]_ algorithm is based on an iterative scheme that alternatively updates the dipole
moments Q by solving a linear least squares problem using a priorconditioned CGLS algorithm with sutable 
stopping condition and updating the hyperparameter theta by an explicit formula.
   
An example of application of IAS to a real dataset can be found in :ref:`example`.
