2    
3            * R/dgeMatrix.R: need solve(<dge>, <sparse>) against infinite
4            recursion in new test in
5            * tests/matprod.R: testing the above and another solve() case, below
6    
7            * R/sparseMatrix.R (lm.fit.sparse): slightly more efficient for
8            e.g. triangular 'x'.
9    
10            * src/dgCMatrix.c (dgCMatrix_qrsol): use AS_CSP() hence allowing dtC*
11            * src/dgCMatrix.c (dgCMatrix_cholsol): use AS_CHM_SP() to work
12            correctly with unit-triangular x
13    
14            * src/dsCMatrix.c (dsCMatrix_Csparse_solve): use AS_CHM_SP()
15            instead of not checking diagU.
16    
17            * R/diagMatrix.R, R/Auxiliaries.R: tweaks to allow later
18            experiments where diagonalMatrix would extend sparse*.

21    2008-07-23  Martin Maechler  <maechler@stat.math.ethz.ch>
22    
23            * src/dgCMatrix.c (compressed_non_0_ij): for nnzero(), use
24            "x@p[ncol(x)]" instead of length(x@i).
25            * R/Auxiliaries.R (nnzero): ditto
26    
27            * src/chm_common.c (as_cholmod_sparse): Do not use LENGTH(islot)
28            since that fails for over-allocated i.
29    
30            * tests/validObj.R: more testing of over-allocated (i,x) slots
31    
32    2008-07-23  Martin Maechler  <maechler@stat.math.ethz.ch>
33    
34            * src/chm_common.c (as_cholmod_sparse): Add 4th argument
35            'sort_in_place' and set it to TRUE in call from
36            * src/Csparse.c (Csparse_validate): sort in place, making sure that
37            validObject() continues sort the columns if needed.
38    
39            * tests/validObj.R: now tests that more thoroughly, and
40            * man/CsparseMatrix-class.Rd: documents it.

43    
44            * src/cs_utils.c (Matrix_as_cs): add check_Udiag switch
45            * src/cs_utils.h (AS_CSP & AS_CSP__): two versions
46            * src/dtCMatrix.c (dtCMatrix_sparse_solve): no longer needs
47            diagU2N().
48    
49          * R/diagMatrix.R (.sparseDiagonal): new utility, used in "old"          * R/diagMatrix.R (.sparseDiagonal): new utility, used in "old"
50          .spDiagonal() and new .trDiagonal().          .spDiagonal() and new .trDiagonal().

83          * [r2215] inst/doc/factor2sparse.Rnw: revive a year-old unfinished          * inst/doc/factor2sparse.Rnw: revive a year-old unfinished vignette
           vignette  
         * [r2214] R/AllGeneric.R: cosmetic  
         * [r2213] man/image-methods.Rd: typo ("non-number" :-\ )
