726    2006-11-01  Douglas Bates  <bates@r-project.org>
727    
728            * R/Csparse.R,src/Csparse.c,tests/matprod.R,
729            man/CsparseMatrix-class.Rd: crossprod(<CsparseMatrix>,
730            <CsparseMatrix>) added
731    
732    2006-10-30  Martin Maechler  <maechler@stat.math.ethz.ch>
733    
734            * tests/matprod.R: add a variation of Harri's example
735    
736            * R/dsparseMatrix.R: fix crossprod(<dsparse>, <dge>) to *not*
737            recursive infinitely.
738    
739            * R/dgCMatrix.R: + solve(<sparse>, <sparse>)
740    
741            * tests/indexing.R: add test for the "<" bug fixed 10-27 in R/dMatrix.R
742    
743    2006-10-28  Martin Maechler  <maechler@stat.math.ethz.ch>
744    
745            * tests/Class+Meth.R (tstMatrixClass): more: use non-trivial
746            matrix if possible; test m+m == 2*m; now test dgRMatrix.
747            * R/dgRMatrix.R (.to.dgR): a few more coercions, in order to
748            satisfy the above test.
749    
750    2006-10-27  Martin Maechler  <maechler@stat.math.ethz.ch>
751    
752            * R/Matrix.R (Ops):  <Matrix> o <matrix>  method added
753    
754            * R/dgCMatrix.R: solve(a, b="missing") based on
755            * src/dgCMatrix.c (dgCMatrix_matrix_solve): extend to work with
756            RHS = NULL.
757    
758            * R/diagMatrix.R (diagdiagprod): extend %*% etc to ldiMatrix;
759            add more (needed) [t]crossprod() methods.
760    
761            * man/ddiMatrix-class.Rd: more info, notably on 'diag'
762    
763            * R/Auxiliaries.R (as_CspClass): cleanup
764            (drop0): internal utility for "Csparse_drop(*, 0)"
765            (.bail.out.2): encourage active feedback
766    
767    2006-10-26  Martin Maechler  <maechler@stat.math.ethz.ch>
768    
769            * R/dMatrix.R(Compare): new(), then slots [no validity check]
770    
771            * src/Csparse.c (Csparse_validate): fixed (and more efficient in
772            non-valid or 'sorted' case).
773    
774            * R/dsparseMatrix.R: add "chol" method.
775            * R/ddenseMatrix.R: ditto
776    
777            * R/diagMatrix.R (Ops): group methods for  <diagonal> o <sparse>
778            * NAMESPACE (Ops)
779            * R/diagMatrix.R (diag2T): simple utility used "higher level"
780            coercion; deprecating direct lower level coercions.
781    
782            * R/*.R (seq): use seq_len() and seq_along() where possible.
783

788    
789    2006-10-20  Douglas Bates  <bates@stat.wisc.edu>
790    
791            * src/init.c (R_init_Matrix): export more cholmod CCallable functions.
792
