1    2008-03-07  Martin Maechler  <maechler@stat.math.ethz.ch>
2    
3            * tests/simple.R: testing diagN2U
4    
5    2008-03-06  Martin Maechler  <maechler@stat.math.ethz.ch>
6    
7            * R/Auxiliaries.R (diagN2U): interface to
8    
9            * src/Csparse.c (Csparse_diagN2U): .Call()able SEXP version of chm_diagN2U()
10    
11            * tests/matprod.R: test for triangularity preserving <dtC> %*% <dtC>
12    
13    2008-03-05  Martin Maechler  <maechler@stat.math.ethz.ch>
14    
15            * src/chm_common.c (chm_diagN2U): new utility.
16    
17            * src/Csparse.c (Csparse_Csparse_crossprod, Csparse_Csparse_prod):
18            make use of chm_diagN2U() and hence now preserve triangularity and
19            unit-triangularity.
20    
21            * DESCRIPTION (LicenseDetails): new; such that 'License:' becomes "canonical"
22    
23    2008-03-04  Martin Maechler  <maechler@stat.math.ethz.ch>
24    
25            * R/diagMatrix.R (subDiag): fix when x[..] became a vector
26    
27            * src/Tsparse.c (Tsparse_diagU2N): new utility, necessary for e.g.
28            * src/Csparse.c (Csparse_crossprod): use [CT]sparse_diagU2N() !!
29    
30            * R/Auxiliaries.R (.diagU2N): make use of new Tsparse_diagU2N
31    
32            * R/Ops.R ("-" (<sparseMatrix>)): use diagU2N()

34            * src/chm_common.c (AS_CHM_FINISH): add note about problem
35            for triangular (diag = "U").
36

38    
39            * R/Auxiliaries.R (as_Csparse2): drop this, replacing by
40            * R/bind.R:  .Call(dense_to_Csparse, *)
41    
42    2008-02-20  Martin Maechler  <maechler@stat.math.ethz.ch>
43    
44            * R/Matrix.R (Matrix): no longer use coercions to specific classes
45                    (since we are discouraging them in user code).
46    
47            * tests/*.R: also replaces coercions to specific classes by
48            coercions to super classes.
49    
50            * R/denseMatrix.R (.dense2C): simplified by using forceSymmetric()
51

57            * src/dense.c (dense_band): generalized from ddense_band
58    
59            * R/ddenseMatrix.R (.trilDense,.triuDense, .bandDense):
60              now for "denseMatrix" (instead of just "ddense*"); much
61              simplified setMethod()s for these.
62    
63            * src/dense.c (dense_to_symmetric): generalized from ddense_*
64    
65    2008-02-18  Martin Maechler  <maechler@stat.math.ethz.ch>
66    
67            * R/AllGeneric.R: forceSymmetric() generic: fast no-checking
68            version of as(*, "symmetricMatric").
69    
70            * src/dense.c (ddense_to_symmetric): add 'symm_test' argument, and
71            * R/symmetricMatrix.R: set it TRUE in coercion to "symmetricMatrix"
72    
73    2008-02-16  Martin Maechler  <maechler@stat.math.ethz.ch>
74    
75            * R/Matrix.R (subset.ij): utility, as first step to faster
76               M [ <ij-matrix> ] indexing.
77    
78            * R/Matrix.R (.M.sub.i.logical): M[ <logical> ] : try better.
79    
80            * src/dense.c (ddense_symmpart, ddense_skewpart): new functions

84    
85            * src/dense.c (ddense_to_symmetric): new function used in
86    
87            * R/symmetricMatrix.R: setAs(., "symmetricMatrix")
88    
89            * R/sparseMatrix.R, et_al (isSymmetric): add '...' to formals, in
90            order to match the generic (and evade .local(..)).
91    
92            * R/dsCMatrix.R: dgC -> dsC: use C code!
93    
94            * NAMESPACE, R/AllGeneric.R (symmpart, skewpart): new functions
95            as per TODO
96    
97            * R/Auxiliaries.R (setZero, all0Matrix): new utilities
98    
99            * R/symmetricMatrix.R: obvious symmpart(), skewpart() methods

105    
106            * R/Auxiliaries.R (non0.i): take out of non0ind
107    
108            * R/ddenseMatrix.R (.trilDense, .triuDense, .bandDense):
109            make tril(), triu(), band() work for "matrix" and all "dense*"
110    
111            * R/triangularMatrix.R (.tri[lu].tr): need .diagU2N(*)
112            * tests/simple.R: test the fix above
113    
114            * R/sparseMatrix.R ([): simplification: no coerce to <general>
115                    before we use as(., <Tsparse>)[...] anyway
116    
117            * R/Rsparse.R (.viaC.to.R): mostly instead of .viaC.to.dgR()
118    
119            * R/triangularMatrix.R (isTriangular): methods for all subclasses
120            instead of "triangularMatrix" -- just to disambiguate
121    
122    2008-02-14  Martin Maechler  <maechler@stat.math.ethz.ch>
123    
124            * tests/Class+Meth.R (dotestMat): add m[FALSE, FALSE] { <-> TODO}

130            * R/Tsparse.R (.TM.sub.i.2col, .TM.repl.i.2col): ditto;
131                    now, M[lower.tri(M)] and  M[lower.tri(M)] <- v  work better
132    
133            * src/Tsparse.c (Tsparse_to_tCsparse): new fast utility.
134            * src/Tsparse.h, init.c: ditto
135            * R/Auxiliaries.R (isTriT): new; faster than going via Csparse
136                 both isTriC() and isTriT() now return TRUE with "kind" or FALSE.
137            * R/sparseMatrix.R (isTriangular): hence simplified
138

140    
141            * R/Ops.R (.Arith.Csparse): new utility factored out of former

151    
152            * R/ngTMatrix.R: allow as(<numeric matrix>, "ngTMatrix") and hence
153            coercion to "nMatrix" and "pMatrix"
154    
155            * R/AllClass.R: "Schur" class;  "number" class union
156            * man/number-class.Rd:
157            * man/Schur-class.Rd:
158    
159            * R/eigen.R (.dgeSchur): utility, and return "Schur" class

170    
171          * R/CHMfactor.R (solve): method for b="numeric", but also b="ANY"          * R/CHMfactor.R (solve): method for b="numeric", but also b="ANY"
