1    2008-08-25  Martin Maechler  <maechler@stat.math.ethz.ch>
2    
3            * src/dgCMatrix.c (dgCMatrix_LU): partially revert change
4            r2175 (2008-04-23) and do give an error for a singular matrix.
5            * R/Auxiliaries.R (detSparseLU): adapt to that.
6    
7            * R/LU.R: expand( <sparseLU> )
8    
9            * NAMESPACE, man/all.equal-methods.Rd:
10            * R/Matrix.R (all.equal): methods for Matrices,
11            * R/sparseMatrix.R, R/sparseVector.R: sparseMatrices and -Vectors
12    
13    
14    2008-08-23  Douglas Bates <bates@stat.wisc.edu>
15    
16            * [r2243] R/CHMfactor.R, man/CHMfactor-class.Rd: Added expand method and
17              documentation for CHMfactor class
18            * [r2241] R/CHMfactor.R: Added trivial coercion method for CHMfactor ->
19              pMatrix
20    
21    2008-08-19  Martin Maechler  <maechler@stat.math.ethz.ch>
22    
23            * R/nsCMatrix.R (setAs(., dgTMatrix))): remove unused method
24    
25    2008-08-18  Martin Maechler  <maechler@stat.math.ethz.ch>
26    
27            * R/Ops.R (.Ops2dge.via.x, and many others): eliminate never-used
28            variable assignments {from "next version" codetools}.
29            * R/Csparse.R, R/Tsparse.R: ditto
30    
31    2008-08-17  Martin Maechler  <maechler@stat.math.ethz.ch>
32    
33            * R/sparseVector.R (sp2vec, coerce to sparseVector):
34            make sure no integer overflows happen, and use double precision
35            (n, index) where appropriate.
36    
37            * tests/Simple.R: test "large" sparse vectors.
38    
39    2008-08-14  Martin Maechler  <maechler@stat.math.ethz.ch>
40    
41            * R/AllClass.R (sparseVector): 'length' and 'i' are "numeric", not
42            just integer (allowing much longer length).
43    
44    2008-07-28  Martin Maechler  <maechler@stat.math.ethz.ch>
45    
46            * R/AllClass.R (diagonalMatrix): extend  "sparseMatrix" instead of
47            "denseMatrix".  This renders "scarceMatrix" dispensable and
48            invalidates part of MM's presentations on "space of Matrix
49            classes", but seems cleaner overall.
50    
51            * R/diagMatrix.R, etc: eliminate "scarceMatrix", replacing it by
52            "sparseMatrix" in method signatures;
53            further, instead of coercing to "sparseMatrix", coerce to
54            "TsparseMatrix" now.
55    
56    2008-07-26  Martin Maechler  <maechler@stat.math.ethz.ch>
57    
58            * src/dgCMatrix.c (dgCMatrix_qrsol): allow third argument 'order' in
59            .Call(.)
60            * R/sparseMatrix.R (lm.fit.sparse), src/dgCMatrix.h, src/init.c: ditto
61    
62    2008-07-24  Martin Maechler  <maechler@stat.math.ethz.ch>
63    
64            * R/dgeMatrix.R: need solve(<dge>, <sparse>) against infinite
65            recursion in new test in
66            * tests/matprod.R: testing the above and another solve() case, below
67    
68            * R/sparseMatrix.R (lm.fit.sparse): slightly more efficient for
69            e.g. triangular 'x'.
70    
71            * src/dgCMatrix.c (dgCMatrix_qrsol): use AS_CSP() hence allowing dtC*
72            * src/dgCMatrix.c (dgCMatrix_cholsol): use AS_CHM_SP() to work
73            correctly with unit-triangular x
74    
75            * src/dsCMatrix.c (dsCMatrix_Csparse_solve): use AS_CHM_SP()
76            instead of not checking diagU.
77    
78            * R/diagMatrix.R, R/Auxiliaries.R: tweaks to allow later
79            experiments where diagonalMatrix would extend sparse*.
80    
81    
82    2008-07-23  Martin Maechler  <maechler@stat.math.ethz.ch>
83    
84            * src/dgCMatrix.c (compressed_non_0_ij): for nnzero(), use
85            "x@p[ncol(x)]" instead of length(x@i).
86            * R/Auxiliaries.R (nnzero): ditto
87    
88            * src/chm_common.c (as_cholmod_sparse): Do not use LENGTH(islot)
89            since that fails for over-allocated i.
90    
91            * tests/validObj.R: more testing of over-allocated (i,x) slots
92    
93    2008-07-23  Martin Maechler  <maechler@stat.math.ethz.ch>
94    
95            * src/chm_common.c (as_cholmod_sparse): Add 4th argument
96            'sort_in_place' and set it to TRUE in call from
97            * src/Csparse.c (Csparse_validate): sort in place, making sure that
98            validObject() continues sort the columns if needed.
99    
100            * tests/validObj.R: now tests that more thoroughly, and
101            * man/CsparseMatrix-class.Rd: documents it.
102

107            * [r2231] src/chm_common.c: check for sorted columns in
108              as_cholmod_sparse instead of assuming it
109            * [r2228] src/cs_utils.c: Use R_alloc for semi-permanent storage when
110              expanding diagonal
111

248    
249            * R/Auxiliaries.R (encodeInd2?): care against integer overflow (for
