1    2008-02-21  Martin Maechler  <maechler@stat.math.ethz.ch>
2    
3            * R/Auxiliaries.R (as_Csparse2): drop this, replacing by
4            * R/bind.R:  .Call(dense_to_Csparse, *)
5    
6    2008-02-20  Martin Maechler  <maechler@stat.math.ethz.ch>
7    
8            * R/Matrix.R (Matrix): no longer use coercions to specific classes
9                    (since we are discouraging them in user code).
10    
11            * tests/*.R: also replaces coercions to specific classes by
12            coercions to super classes.
13    
14            * R/denseMatrix.R (.dense2C): simplified by using forceSymmetric()
15    
16    
17    2008-02-19  Martin Maechler  <maechler@stat.math.ethz.ch>
18    
19            * man/CAex.Rd: example: coerce to symmetric*, not dsC*
20    
21            * src/dense.c (dense_band): generalized from ddense_band
22    
23            * R/ddenseMatrix.R (.trilDense,.triuDense, .bandDense):
24              now for "denseMatrix" (instead of just "ddense*"); much
25              simplified setMethod()s for these.
26    
27            * src/dense.c (dense_to_symmetric): generalized from ddense_*
28    
29    2008-02-18  Martin Maechler  <maechler@stat.math.ethz.ch>
30    
31            * R/AllGeneric.R: forceSymmetric() generic: fast no-checking
32            version of as(*, "symmetricMatric").
33    
34            * src/dense.c (ddense_to_symmetric): add 'symm_test' argument, and
35            * R/symmetricMatrix.R: set it TRUE in coercion to "symmetricMatrix"
36    
37    2008-02-16  Martin Maechler  <maechler@stat.math.ethz.ch>
38    
39            * R/Matrix.R (subset.ij): utility, as first step to faster
40               M [ <ij-matrix> ] indexing.
41    
42            * R/Matrix.R (.M.sub.i.logical): M[ <logical> ] : try better.
43    
44            * src/dense.c (ddense_symmpart, ddense_skewpart): new functions
45            for more efficient symmpart() and skewpart() methods.
46    
47            * src/Mutils.c (equal_string_vectors): utility
48    
49            * src/dense.c (ddense_to_symmetric): new function used in
50    
51            * R/symmetricMatrix.R: setAs(., "symmetricMatrix")
52    
53            * R/sparseMatrix.R, et_al (isSymmetric): add '...' to formals, in
54            order to match the generic (and evade .local(..)).
55    
56            * R/dsCMatrix.R: dgC -> dsC: use C code!
57    
58            * NAMESPACE, R/AllGeneric.R (symmpart, skewpart): new functions
59            as per TODO
60    
61            * R/Auxiliaries.R (setZero, all0Matrix): new utilities
62    
63            * R/symmetricMatrix.R: obvious symmpart(), skewpart() methods
64    
65    
66    2008-02-15  Martin Maechler  <maechler@stat.math.ethz.ch>
67    
68            * R/Ops.R (.Arith.Csparse): use diagU2N when needed in triangular
69    
70            * R/Auxiliaries.R (non0.i): take out of non0ind
71    
72            * R/ddenseMatrix.R (.trilDense, .triuDense, .bandDense):
73            make tril(), triu(), band() work for "matrix" and all "dense*"
74    
75            * R/triangularMatrix.R (.tri[lu].tr): need .diagU2N(*)
76            * tests/simple.R: test the fix above
77    
78            * R/sparseMatrix.R ([): simplification: no coerce to <general>
79                    before we use as(., <Tsparse>)[...] anyway
80    
81            * R/Rsparse.R (.viaC.to.R): mostly instead of .viaC.to.dgR()
82    
83            * R/triangularMatrix.R (isTriangular): methods for all subclasses
84            instead of "triangularMatrix" -- just to disambiguate
85    
86    2008-02-14  Martin Maechler  <maechler@stat.math.ethz.ch>
87    
88            * tests/Class+Meth.R (dotestMat): add m[FALSE, FALSE] { <-> TODO}

92    
93            * R/Matrix.R (.M.sub.i.2col): fix for logical matrix indexing
94            * R/Tsparse.R (.TM.sub.i.2col, .TM.repl.i.2col): ditto;
95                    now, M[lower.tri(M)] and  M[lower.tri(M)] <- v  work better
96    
97            * src/Tsparse.c (Tsparse_to_tCsparse): new fast utility.
98            * src/Tsparse.h, init.c: ditto
99            * R/Auxiliaries.R (isTriT): new; faster than going via Csparse
100                 both isTriC() and isTriT() now return TRUE with "kind" or FALSE.
101            * R/sparseMatrix.R (isTriangular): hence simplified
102    
103    2008-01-24  Martin Maechler  <maechler@stat.math.ethz.ch>
104    
105            * R/Ops.R (.Arith.Csparse): new utility factored out of former
106              <dgC> o <dgC>, extended for triangular and also used in  <dtC> o <dtC>.

115    
116            * R/ngTMatrix.R: allow as(<numeric matrix>, "ngTMatrix") and hence
117            coercion to "nMatrix" and "pMatrix"
118    
119            * R/AllClass.R: "Schur" class;  "number" class union
120            * man/number-class.Rd:
121            * man/Schur-class.Rd:
122

135            * R/CHMfactor.R (solve): method for b="numeric", but also b="ANY"

137                    formals()$system instead of cut&paste.
138            * tests/factorizing.R: test solve(<CHM..>, <numeric>)
139
