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

84    
85            * src/cs_utils.c (Matrix_as_cs): add check_Udiag switch
86            * src/cs_utils.h (AS_CSP & AS_CSP__): two versions
87            * src/dtCMatrix.c (dtCMatrix_sparse_solve): no longer needs
88            diagU2N().
89    
90          * R/diagMatrix.R (.sparseDiagonal): new utility, used in "old"          * R/diagMatrix.R (.sparseDiagonal): new utility, used in "old"
91          .spDiagonal() and new .trDiagonal().          .spDiagonal() and new .trDiagonal().
