28    2008-08-25  Martin Maechler  <maechler@stat.math.ethz.ch>
29    
30            * src/dgCMatrix.c (dgCMatrix_LU): partially revert change
31            r2175 (2008-04-23) and do give an error for a singular matrix.
32            * man/lu.Rd, R/Auxiliaries.R (detSparseLU): adapt to that.
33    
34            * R/LU.R: expand( <sparseLU> )

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

49    
50            * R/nsCMatrix.R (setAs(., dgTMatrix))): remove unused method
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
69            just integer (allowing much longer length).
70    
71    2008-07-28  Martin Maechler  <maechler@stat.math.ethz.ch>
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>

86            .Call(.)
87            * R/sparseMatrix.R (lm.fit.sparse), src/dgCMatrix.h, src/init.c: ditto
88    
89    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    2008-07-23  Martin Maechler  <maechler@stat.math.ethz.ch>
110    
111            * 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>
121    
122            * src/chm_common.c (as_cholmod_sparse): Add 4th argument
123            'sort_in_place' and set it to TRUE in call from

125            validObject() continues sort the columns if needed.
126    
127            * tests/validObj.R: now tests that more thoroughly, and
128            * man/CsparseMatrix-class.Rd: documents it.

1452            objects.
1453    
1454            * tests/Class+Meth.R (tstMatrixClass): now testing diag(), nnzero(),
1455              and more of "!", "&", "|", all, any; coercions
1456    
1457            * R/Rsparse.R: many coercions (which enable quite a few other
1458            methods), thanks to enhancements in
1459            * src/dgCMatrix.c (R_to_CMatrix): new, and
1460            * src/dgCMatrix.c (compressed_to_TMatrix): now for (d,l,n) ,
1461            symmetric & triangular and ..RMatrix objects.
1462    
1463            * src/TMatrix_as.c (Matrix_T_as_DENSE,Matrix_T_as_GENERAL):
1464            renamed file from src/dsTMatrix.c;
1465            now dealing with symmetric and triangular Tsparse coercions, both
1466            to dense and general.
1467    
1468    2007-01-27  Martin Maechler  <maechler@stat.math.ethz.ch>
1469    
1470            * src/dsTMatrix.c: has now "l" and "n" methods besides the "d" ones.
1471    
1472            * R/Ops.R (Arith): <dgCMatrix> o <numeric> now remains sparse
1473            where sensible when the <numeric> is of length > 1.
1474    
1475    2007-01-26  Martin Maechler  <maechler@stat.math.ethz.ch>
1476    
1477            * R/Matrix.R ([<-): for M[] <- value: fix length

1489    
1490    2007-01-18  Martin Maechler  <maechler@stat.math.ethz.ch>
1491    
1492            * src/Mutils.h (SET_DimNames): new utility

1503    
1504            * R/Auxiliaries.R (as_Csparse): and quite a few others:
1505                    allow to pass class definition --> speedup
1506            * R/sparseMatrix.R: apply the above
1507    
1508            * R/Csparse.R: coercion Csparse* to dense* now preserves shape properties.
1509    
1510            * src/Mutils.h (mMatrix_as_geMatrix): new, based on
1511            * src/Mutils.c (dup_mMatrix_as_geMatrix): new; generalization of
1512            old dup_mMatrix_as_dgeMatrix), eliminating a long-standing "FIXME".
1513    
1514            * src/dense.c (dense_to_Csparse): use new mMatrix_as_geMatrix()
1515    
1516            * R/denseMatrix.R (.dense2C): based on dense_to_Csparse: name it,
1517            and use it for "sparse*" as well, since it's faster than the
1518            as_Csparse(.) way.
1519    
1520    2007-01-15  Martin Maechler  <maechler@stat.math.ethz.ch>

1528            * R/Csparse.R:: go via Tsparse for "M[ij] <- v"
1529    
1530            * R/Ops.R: "Compare" for (C|R)sparse: need pointer slot for all
1531            FALSE answer
1532    
1533            * R/Csparse.R (replCmat): fix the "all non-zero" case with reordering
1534            * tests/indexing.R: test it, and some of the above

1550    
1551            * R/Ops.R ("Arith" etc): move almost all "Ops" methods to new R
1552            file; start using "Logic", hence
1553    
1554            * DESCRIPTION (Depends): R >= 2.4.1 (since we want "Logic")
1555            * NAMESPACE: import and export "Logic"
1556    
1557    2006-12-27  Martin Maechler  <maechler@stat.math.ethz.ch>
1558

1614    
1615            * R/sparseMatrix.R (prSpMatrix): "." alignment much improved:
1616            align with proper position of "0", i.e., right for integers.
1617            argument 'align' by default is "fancy".
1618

1620    
1621            * R/sparseMatrix.R: delegate "Compare" to "Csparse.."

1643            to LL before converting to a sparse matrix. (The LDL form can be
1644            converted to a sparse matrix but it is implicitly a unit
1645            triangular matrix and a diagonal matrix overwritten on the diagonal.)
