Changes in version 0.11-0 (2016-03-10)                 

NEW FEATURES

    o   Now rARPACK becomes a simple shell of the RSpectra package.

                 Changes in version 0.10-0 (2016-01-18)                 

BUG FIXES

    o   Updated the backend Spectra library, which fixed the
	compatibility with Eigen >= 3.2.6

                 Changes in version 0.9-0 (2015-11-18)                  

BUG FIXES

    o   Fixed a bug that causes the algorithm not converging on some
	matrices

                 Changes in version 0.8-1 (2015-11-01)                  

BUG FIXES

    o   Fixed a compilation problem on Solaris

                 Changes in version 0.8-0 (2015-10-31)                  

NEW FEATURES

    o   The backend program is now changed from ARPACK to Spectra,
	which brings cleaner code and better performance.

    o   eigs_sym() now accepts more matrix types.

    o   Added a C interface for other packages to link to.

BUG FIXES

    o   Fixed a bug reported by xshi19 (#8)

    o   Fixed a performance issue reported by swajnautcz (#10)

                 Changes in version 0.7-0 (2014-11-03)                  

NEW FEATURES

    o   Support for implicit matrix, contributed by Jiali Mei.  User
	can supply a function FUN rather than an explicit matrix to
	eigs(), and the eigenvalues/eigenvectors of this operator will
	be computed. FUN(x, args) must return a vector of the same
	length as x.

    o   eigs() will test the symmetry of matrix before actual
	computation, since symmetric matrices can guarantee real
	eigenvalues and eigenvectors, and the numerical result is more
	stable.

BUG FIXES

    o   C++ code of svds() is completely rewritten. Now it is more
	readable and easier to maintain.

    o   Fix a bug possibly coming from ARPACK, which sometimes gives
	incorrect result of complex eigenvectors.

    o   Avoid using a C random number generator.

                 Changes in version 0.6-0 (2014-08-24)                  

NEW FEATURES

    o   Add support for new matrix types: *dgeMatrix* and *dgRMatrix*.

    o   eigs() now allows a full Eigen Decomposition, meaning that all
	the eigenvalues are calculated. In this case eigs() is simply a
	wrapper of eigen(), and with a warning issued.

    o   Ditto for svds().

BUG FIXES

    o   Rewrite C++ code using classes and templates.

    o   Fix errors in checking the values of k and ncv.

                 Changes in version 0.5-0 (2014-01-19)                  

NEW FEATURES

    o   Add svds() function to calculate truncated SVD.

BUG FIXES

    o   Now sort eigenvalues in decreasing order.

    o   Rename eigs.sym() to eigs_sym() to avoid confusion.

    o   Fix a matrix out-of-bound error.

                        Changes in version 0.4-0                        

NEW FEATURES

    o   Implement shift-and-invert mode for all supported eigen
	problems.

BUG FIXES

    o   Update arpack-ng to 3.1.4.

                        Changes in version 0.3-0                        

NEW FEATURES

    o   Now eigs() supports real symmetric matrices.

                        Changes in version 0.2-0                        

NEW FEATURES

    o   Now eigs() supports sparse real nonsymmetric matrices of the
	class *dgCMatrix*, defined in the Matrix package.

                        Changes in version 0.1-0                        

NEW FEATURES

    o   Initial version. For now eigs() supports dense real
	nonsymmetric matrices.
