Detailed DescriptionNamespace "emsunfold" (EMS stands for Expectation-Maximization with Smoothing) is used for classes and functions in the NPStat package which implement EMS unfolding and rely on the Eigen package for sparse linear algebra. See http://eigen.tuxfamily.org/ Typedef Documentation◆ StaticSparseUnfoldingFilterNDReader
Factory for deserializing filters representable by sparse matrices Function Documentation◆ pruneCovariance()
template<class Matrix >
This function will prune off-diagonal elements of a sparse symmetric positive-semidefinite matrix which correspond to correlation coefficients smaller in magnitude than "tol". This function will also make sure that the correlation coefficients do not exceed 1 in magnitude. ◆ trlanEigensystem()
template<class Matrix >
Determine eigenvalues and eigenvectors of the argument covariance matrix using TRLAN, steered by the parameters given. This function returns the TRLAN error code (status). 0 means everything is OK. Consult the TRLAN user guide for the meaning of other error codes. Note that, even when 0 is returned, the number of eigenpairs actually found could be less than the number of eigenpairs requested and/or tail fraction stopping condition might not be satisfied. The eigenvalues will be returned in the increasing order. Check diagnostics->nConverged() to see how many of them are returned. Note that the vector of eigenvalues can actually have more elements, but only "diagnostics->nConverged()" of them are valid. Eigenvectors will be placed into "eigenvectors" vector one after another. If the matrix "covmat" has "nrows" rows then &eigenvectors[0] will point to the first eigenvector, &eigenvectors[0] + nrows to the second, etc. The order of eigenvectors corresponds to the order of eigenvalues.
