1    2008-08-25  Martin Maechler  <maechler@stat.math.ethz.ch>
2    
3            * R/LU.R: expand( <sparseLU> )
4    
5            * NAMESPACE, man/all.equal-methods.Rd:
6            * R/Matrix.R (all.equal): methods for Matrices,
7            * R/sparseMatrix.R, R/sparseVector.R: sparseMatrices and -Vectors
8    
9    
10    2008-08-23  Douglas Bates <bates@stat.wisc.edu>
11    
12            * [r2243] R/CHMfactor.R, man/CHMfactor-class.Rd: Added expand method and
13              documentation for CHMfactor class
14            * [r2241] R/CHMfactor.R: Added trivial coercion method for CHMfactor ->
15              pMatrix
16    
17    2008-08-19  Martin Maechler  <maechler@stat.math.ethz.ch>
18    
19            * R/nsCMatrix.R (setAs(., dgTMatrix))): remove unused method
20    
21    2008-08-18  Martin Maechler  <maechler@stat.math.ethz.ch>
22    
23            * R/Ops.R (.Ops2dge.via.x, and many others): eliminate never-used
24            variable assignments {from "next version" codetools}.
25            * R/Csparse.R, R/Tsparse.R: ditto
26    
27    2008-08-17  Martin Maechler  <maechler@stat.math.ethz.ch>
28    
29            * R/sparseVector.R (sp2vec, coerce to sparseVector):
30            make sure no integer overflows happen, and use double precision
31            (n, index) where appropriate.
32    
33            * tests/Simple.R: test "large" sparse vectors.
34    
35    2008-08-14  Martin Maechler  <maechler@stat.math.ethz.ch>
36    
37            * R/AllClass.R (sparseVector): 'length' and 'i' are "numeric", not
38            just integer (allowing much longer length).
39    
40    2008-07-28  Martin Maechler  <maechler@stat.math.ethz.ch>
41    
42            * R/AllClass.R (diagonalMatrix): extend  "sparseMatrix" instead of
43            "denseMatrix".  This renders "scarceMatrix" dispensable and
44            invalidates part of MM's presentations on "space of Matrix
45            classes", but seems cleaner overall.
46    
47            * R/diagMatrix.R, etc: eliminate "scarceMatrix", replacing it by
48            "sparseMatrix" in method signatures;
49            further, instead of coercing to "sparseMatrix", coerce to
50            "TsparseMatrix" now.
51    
52    2008-07-26  Martin Maechler  <maechler@stat.math.ethz.ch>
53    
54            * src/dgCMatrix.c (dgCMatrix_qrsol): allow third argument 'order' in
55            .Call(.)
56            * R/sparseMatrix.R (lm.fit.sparse), src/dgCMatrix.h, src/init.c: ditto
57    
58    2008-07-24  Martin Maechler  <maechler@stat.math.ethz.ch>
59    
60            * R/dgeMatrix.R: need solve(<dge>, <sparse>) against infinite
61            recursion in new test in
62            * tests/matprod.R: testing the above and another solve() case, below
63    
64            * R/sparseMatrix.R (lm.fit.sparse): slightly more efficient for
65            e.g. triangular 'x'.
66    
67            * src/dgCMatrix.c (dgCMatrix_qrsol): use AS_CSP() hence allowing dtC*
68            * src/dgCMatrix.c (dgCMatrix_cholsol): use AS_CHM_SP() to work
69            correctly with unit-triangular x
70    
71            * src/dsCMatrix.c (dsCMatrix_Csparse_solve): use AS_CHM_SP()
72            instead of not checking diagU.
73    
74            * R/diagMatrix.R, R/Auxiliaries.R: tweaks to allow later
75            experiments where diagonalMatrix would extend sparse*.
76    
77    
78    2008-07-23  Martin Maechler  <maechler@stat.math.ethz.ch>
79    
80            * src/dgCMatrix.c (compressed_non_0_ij): for nnzero(), use
81            "x@p[ncol(x)]" instead of length(x@i).
82            * R/Auxiliaries.R (nnzero): ditto
83    
84            * src/chm_common.c (as_cholmod_sparse): Do not use LENGTH(islot)
85            since that fails for over-allocated i.
86    
87            * tests/validObj.R: more testing of over-allocated (i,x) slots
88    
89    2008-07-23  Martin Maechler  <maechler@stat.math.ethz.ch>
90    
91            * src/chm_common.c (as_cholmod_sparse): Add 4th argument
92            'sort_in_place' and set it to TRUE in call from
93            * src/Csparse.c (Csparse_validate): sort in place, making sure that
94            validObject() continues sort the columns if needed.
95    
96            * tests/validObj.R: now tests that more thoroughly, and
97            * man/CsparseMatrix-class.Rd: documents it.
98    
99    2008-07-22  Douglas Bates <bates@stat.wisc.edu>
100    
101            * [r2233] src/chm_common.c: sort columns more carefully in
102              as_cholmod_sparse
103            * [r2231] src/chm_common.c: check for sorted columns in
104              as_cholmod_sparse instead of assuming it
105            * [r2228] src/cs_utils.c: Use R_alloc for semi-permanent storage when
106              expanding diagonal
107

110    
111            * src/cs_utils.c (Matrix_as_cs): add check_Udiag switch
112            * src/cs_utils.h (AS_CSP & AS_CSP__): two versions
113            * src/dtCMatrix.c (dtCMatrix_sparse_solve): no longer needs
114            diagU2N().
115    
116          * R/diagMatrix.R (.sparseDiagonal): new utility, used in "old"          * R/diagMatrix.R (.sparseDiagonal): new utility, used in "old"
117          .spDiagonal() and new .trDiagonal().          .spDiagonal() and new .trDiagonal().

141    
142            * [r2220] src/dtCMatrix.c: Correct number of columns for rhs in
143              dtCMatrix_sparse_solve
144            * [r2219] src/cs_utils.c: eye->nz should be -1 for compressed column
145              storage
