2    
3            * R/Ops.R (Compare(<Csparse>,<Csparse>): fix for nsparseMatrix
4    
5    2008-08-27  Douglas Bates <bates@stat.wisc.edu>
6    
7            * R/sparseMatrix.R: fac2sparse() for NA's
8    
9    2008-08-26  Martin Maechler  <maechler@stat.math.ethz.ch>
10    
11            * R/sparseVector.R (all.equal.sparseV): make work for nsparseVector's
12    
13    2008-08-25  Martin Maechler  <maechler@stat.math.ethz.ch>
14    
15            * src/dgCMatrix.c (dgCMatrix_LU): partially revert change
16            r2175 (2008-04-23) and do give an error for a singular matrix.
17            * man/lu.Rd, R/Auxiliaries.R (detSparseLU): adapt to that.
18    
19            * R/LU.R: expand( <sparseLU> )
20    
21            * NAMESPACE, man/all.equal-methods.Rd:
22            * R/Matrix.R (all.equal): methods for Matrices,
23            * R/sparseMatrix.R, R/sparseVector.R: sparseMatrices and -Vectors
24    
25    
26    2008-08-23  Douglas Bates <bates@stat.wisc.edu>
27    
28            * [r2243] R/CHMfactor.R, man/CHMfactor-class.Rd: Added expand method and
29              documentation for CHMfactor class
30            * [r2241] R/CHMfactor.R: Added trivial coercion method for CHMfactor ->
31              pMatrix
32    
33    2008-08-19  Martin Maechler  <maechler@stat.math.ethz.ch>
34    
35            * R/nsCMatrix.R (setAs(., dgTMatrix))): remove unused method
36    
37    2008-08-18  Martin Maechler  <maechler@stat.math.ethz.ch>
38    
39            * R/Ops.R (.Ops2dge.via.x, and many others): eliminate never-used
40            variable assignments {from "next version" codetools}.
41            * R/Csparse.R, R/Tsparse.R: ditto
42    
43    2008-08-17  Martin Maechler  <maechler@stat.math.ethz.ch>
44    
45            * R/sparseVector.R (sp2vec, coerce to sparseVector):
46            make sure no integer overflows happen, and use double precision
47            (n, index) where appropriate.
48    
49            * tests/Simple.R: test "large" sparse vectors.
50    
51    2008-08-14  Martin Maechler  <maechler@stat.math.ethz.ch>
52    
53            * R/AllClass.R (sparseVector): 'length' and 'i' are "numeric", not
54            just integer (allowing much longer length).
55    
56    2008-07-28  Martin Maechler  <maechler@stat.math.ethz.ch>
57    
58            * R/AllClass.R (diagonalMatrix): extend  "sparseMatrix" instead of
59            "denseMatrix".  This renders "scarceMatrix" dispensable and
60            invalidates part of MM's presentations on "space of Matrix
61            classes", but seems cleaner overall.
62    
63            * R/diagMatrix.R, etc: eliminate "scarceMatrix", replacing it by
64            "sparseMatrix" in method signatures;
65            further, instead of coercing to "sparseMatrix", coerce to
66            "TsparseMatrix" now.
67    
68    2008-07-26  Martin Maechler  <maechler@stat.math.ethz.ch>
69    
70            * src/dgCMatrix.c (dgCMatrix_qrsol): allow third argument 'order' in
71            .Call(.)
72            * R/sparseMatrix.R (lm.fit.sparse), src/dgCMatrix.h, src/init.c: ditto
73    
74    2008-07-24  Martin Maechler  <maechler@stat.math.ethz.ch>
75    
76            * R/dgeMatrix.R: need solve(<dge>, <sparse>) against infinite
77            recursion in new test in
78            * tests/matprod.R: testing the above and another solve() case, below
79    
80            * R/sparseMatrix.R (lm.fit.sparse): slightly more efficient for
81            e.g. triangular 'x'.
82    
83            * src/dgCMatrix.c (dgCMatrix_qrsol): use AS_CSP() hence allowing dtC*
84            * src/dgCMatrix.c (dgCMatrix_cholsol): use AS_CHM_SP() to work
85            correctly with unit-triangular x
86    
87            * src/dsCMatrix.c (dsCMatrix_Csparse_solve): use AS_CHM_SP()
88            instead of not checking diagU.
89    
90            * R/diagMatrix.R, R/Auxiliaries.R: tweaks to allow later
91            experiments where diagonalMatrix would extend sparse*.
92    
93    
94    2008-07-23  Martin Maechler  <maechler@stat.math.ethz.ch>
95    
96            * src/dgCMatrix.c (compressed_non_0_ij): for nnzero(), use
97            "x@p[ncol(x)]" instead of length(x@i).
98            * R/Auxiliaries.R (nnzero): ditto
99    
100            * src/chm_common.c (as_cholmod_sparse): Do not use LENGTH(islot)
101            since that fails for over-allocated i.
102    
103            * tests/validObj.R: more testing of over-allocated (i,x) slots
104    
105    2008-07-23  Martin Maechler  <maechler@stat.math.ethz.ch>
106    
107            * src/chm_common.c (as_cholmod_sparse): Add 4th argument
108            'sort_in_place' and set it to TRUE in call from
109            * src/Csparse.c (Csparse_validate): sort in place, making sure that
110            validObject() continues sort the columns if needed.
111    
112            * tests/validObj.R: now tests that more thoroughly, and
113            * man/CsparseMatrix-class.Rd: documents it.
114    
115    2008-07-22  Douglas Bates <bates@stat.wisc.edu>
116    
117            * [r2233] src/chm_common.c: sort columns more carefully in
118              as_cholmod_sparse
119            * [r2231] src/chm_common.c: check for sorted columns in
120              as_cholmod_sparse instead of assuming it
121            * [r2228] src/cs_utils.c: Use R_alloc for semi-permanent storage when
122              expanding diagonal
123

159              dtCMatrix_sparse_solve
160            * [r2219] src/cs_utils.c: eye->nz should be -1 for compressed column
161              storage
