_A_r_g_u_m_e_n_t_s:

   prNCP: The output object of 'proposeNCP'.

     tol: Tolerance level for convergence.

   maxit: Maximum number of iterations to allow for convergence.

      mu: Learning paramter for fixed point algorithm. This has already
          been optimised.

_V_a_l_u_e:

     A list with following components: 

       A: Estimate of the mixing matrix.

       B: Estimate of the inverse mixing matrix.

       S: Estimate of the source matrix.

       X: Normalised data matrix.

     ncp: Number of independent components.

      NC: Binary number specifying whether best run converged,0, or
          not,1.

      LL: Log likelihood value of best run.
