27    
28    2008-08-25  Martin Maechler  <maechler@stat.math.ethz.ch>
29    
30            * src/dgCMatrix.c (dgCMatrix_LU): partially revert change
31            r2175 (2008-04-23) and do give an error for a singular matrix.
32            * man/lu.Rd, R/Auxiliaries.R (detSparseLU): adapt to that.
33    
34            * R/LU.R: expand( <sparseLU> )
35

39    
40    
41    2008-08-23  Douglas Bates <bates@stat.wisc.edu>
42    
43            * [r2243] R/CHMfactor.R, man/CHMfactor-class.Rd: Added expand method and
44              documentation for CHMfactor class
45            * [r2241] R/CHMfactor.R: Added trivial coercion method for CHMfactor ->
46              pMatrix
47    
48    2008-08-19  Martin Maechler  <maechler@stat.math.ethz.ch>
49    
50            * R/nsCMatrix.R (setAs(., dgTMatrix))): remove unused method
51    
52    2008-08-18  Martin Maechler  <maechler@stat.math.ethz.ch>
53    
54            * R/Ops.R (.Ops2dge.via.x, and many others): eliminate never-used
55            variable assignments {from "next version" codetools}.
56            * R/Csparse.R, R/Tsparse.R: ditto
57    
58    2008-08-17  Martin Maechler  <maechler@stat.math.ethz.ch>
59    
60            * R/sparseVector.R (sp2vec, coerce to sparseVector):
61            make sure no integer overflows happen, and use double precision
62            (n, index) where appropriate.
63    
64            * tests/Simple.R: test "large" sparse vectors.
65    
66    2008-08-14  Martin Maechler  <maechler@stat.math.ethz.ch>
67    
68            * R/AllClass.R (sparseVector): 'length' and 'i' are "numeric", not
69            just integer (allowing much longer length).
70    
71    2008-07-28  Martin Maechler  <maechler@stat.math.ethz.ch>
72    
73            * R/AllClass.R (diagonalMatrix): extend  "sparseMatrix" instead of
74            "denseMatrix".  This renders "scarceMatrix" dispensable and
75            invalidates part of MM's presentations on "space of Matrix
76            classes", but seems cleaner overall.
77    
78            * R/diagMatrix.R, etc: eliminate "scarceMatrix", replacing it by
79            "sparseMatrix" in method signatures;
80            further, instead of coercing to "sparseMatrix", coerce to
81            "TsparseMatrix" now.
82    
83    2008-07-26  Martin Maechler  <maechler@stat.math.ethz.ch>
84    
85            * src/dgCMatrix.c (dgCMatrix_qrsol): allow third argument 'order' in
86            .Call(.)
87            * R/sparseMatrix.R (lm.fit.sparse), src/dgCMatrix.h, src/init.c: ditto
88    
89    2008-07-24  Martin Maechler  <maechler@stat.math.ethz.ch>
90    
91            * R/dgeMatrix.R: need solve(<dge>, <sparse>) against infinite
92            recursion in new test in
93            * tests/matprod.R: testing the above and another solve() case, below
94    
95            * R/sparseMatrix.R (lm.fit.sparse): slightly more efficient for
96            e.g. triangular 'x'.
97    
98            * src/dgCMatrix.c (dgCMatrix_qrsol): use AS_CSP() hence allowing dtC*
99            * src/dgCMatrix.c (dgCMatrix_cholsol): use AS_CHM_SP() to work
100            correctly with unit-triangular x
101    
102            * src/dsCMatrix.c (dsCMatrix_Csparse_solve): use AS_CHM_SP()
103            instead of not checking diagU.
104    
105            * R/diagMatrix.R, R/Auxiliaries.R: tweaks to allow later
106            experiments where diagonalMatrix would extend sparse*.
107    
108    
109    2008-07-23  Martin Maechler  <maechler@stat.math.ethz.ch>
110    
111            * src/dgCMatrix.c (compressed_non_0_ij): for nnzero(), use
112            "x@p[ncol(x)]" instead of length(x@i).
113            * R/Auxiliaries.R (nnzero): ditto
114    
115            * src/chm_common.c (as_cholmod_sparse): Do not use LENGTH(islot)
116            since that fails for over-allocated i.
117    
118            * tests/validObj.R: more testing of over-allocated (i,x) slots
119    
120    2008-07-23  Martin Maechler  <maechler@stat.math.ethz.ch>
121    
122            * src/chm_common.c (as_cholmod_sparse): Add 4th argument
123            'sort_in_place' and set it to TRUE in call from
124            * src/Csparse.c (Csparse_validate): sort in place, making sure that
125            validObject() continues sort the columns if needed.
126    
127            * tests/validObj.R: now tests that more thoroughly, and
128            * man/CsparseMatrix-class.Rd: documents it.
129    
130    2008-07-22  Douglas Bates <bates@stat.wisc.edu>
131    
132            * [r2233] src/chm_common.c: sort columns more carefully in
133              as_cholmod_sparse
134            * [r2231] src/chm_common.c: check for sorted columns in
135              as_cholmod_sparse instead of assuming it
136            * [r2228] src/cs_utils.c: Use R_alloc for semi-permanent storage when
137              expanding diagonal
138

141    
142            * src/cs_utils.c (Matrix_as_cs): add check_Udiag switch
143            * src/cs_utils.h (AS_CSP & AS_CSP__): two versions
144            * src/dtCMatrix.c (dtCMatrix_sparse_solve): no longer needs
145            diagU2N().
146    
147          * R/diagMatrix.R (.sparseDiagonal): new utility, used in "old"          * R/diagMatrix.R (.sparseDiagonal): new utility, used in "old"
148          .spDiagonal() and new .trDiagonal().          .spDiagonal() and new .trDiagonal().

174              dtCMatrix_sparse_solve
175            * [r2219] src/cs_utils.c: eye->nz should be -1 for compressed column
