30 : mmaechler 2247 * src/dgCMatrix.c (dgCMatrix_LU): partially revert change

39 :    
40 :    
41 : dmbates 2244 2008-08-23 Douglas Bates <bates@stat.wisc.edu>
42 :

49 :

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

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>

88 :    
89 : mmaechler 2237 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 : mmaechler 2235 2008-07-23 Martin Maechler <maechler@stat.math.ethz.ch>
110 :    
111 : mmaechler 2236 * 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>
