1    2008-02-16  Martin Maechler  <maechler@stat.math.ethz.ch>
2    
3            * R/Matrix.R (subset.ij): utility, as first step to faster
4               M [ <ij-matrix> ] indexing.
5    
6            * R/Matrix.R (.M.sub.i.logical): M[ <logical> ] : try better.
7    
8            * src/dense.c (ddense_symmpart, ddense_skewpart): new functions
9            for more efficient symmpart() and skewpart() methods.
10    
11            * src/Mutils.c (equal_string_vectors): utility
12    
13            * src/dense.c (ddense_to_symmetric): new function used in
14    
15            * R/symmetricMatrix.R: setAs(., "symmetricMatrix")
16    
17            * R/sparseMatrix.R, et_al (isSymmetric): add '...' to formals, in
18            order to match the generic (and evade .local(..)).
19    
20            * R/dsCMatrix.R: dgC -> dsC: use C code!
21    
22            * NAMESPACE, R/AllGeneric.R (symmpart, skewpart): new functions
23            as per TODO
24    
25            * R/Auxiliaries.R (setZero, all0Matrix): new utilities
26    
27            * R/symmetricMatrix.R: obvious symmpart(), skewpart() methods
28    
29    
30    2008-02-15  Martin Maechler  <maechler@stat.math.ethz.ch>
31    
32            * R/Ops.R (.Arith.Csparse): use diagU2N when needed in triangular
33    
34            * R/Auxiliaries.R (non0.i): take out of non0ind
35    
36            * R/ddenseMatrix.R (.trilDense, .triuDense, .bandDense):
37            make tril(), triu(), band() work for "matrix" and all "dense*"
38    
39            * R/triangularMatrix.R (.tri[lu].tr): need .diagU2N(*)
40            * tests/simple.R: test the fix above
41    
42            * R/sparseMatrix.R ([): simplification: no coerce to <general>
43                    before we use as(., <Tsparse>)[...] anyway
44    
45            * R/Rsparse.R (.viaC.to.R): mostly instead of .viaC.to.dgR()
46    
47            * R/triangularMatrix.R (isTriangular): methods for all subclasses
48            instead of "triangularMatrix" -- just to disambiguate
49    
50    2008-02-14  Martin Maechler  <maechler@stat.math.ethz.ch>
51    
52            * tests/Class+Meth.R (dotestMat): add m[FALSE, FALSE] { <-> TODO}
53            * tests/indexing.R: example that fails above
54    
55    2008-01-26  Martin Maechler  <maechler@stat.math.ethz.ch>
56    
57            * R/Matrix.R (.M.sub.i.2col): fix for logical matrix indexing
58            * R/Tsparse.R (.TM.sub.i.2col, .TM.repl.i.2col): ditto;
59                    now, M[lower.tri(M)] and  M[lower.tri(M)] <- v  work better
60    
61            * src/Tsparse.c (Tsparse_to_tCsparse): new fast utility.
62            * src/Tsparse.h, init.c: ditto
63            * R/Auxiliaries.R (isTriT): new; faster than going via Csparse
64                 both isTriC() and isTriT() now return TRUE with "kind" or FALSE.
65            * R/sparseMatrix.R (isTriangular): hence simplified
66    
67    2008-01-24  Martin Maechler  <maechler@stat.math.ethz.ch>
68    
69            * R/Ops.R (.Arith.Csparse): new utility factored out of former
70              <dgC> o <dgC>, extended for triangular and also used in  <dtC> o <dtC>.
71    
72    2008-01-23  Martin Maechler  <maechler@stat.math.ethz.ch>
73    
74            * tests/factorizing.R (checkSchur): and more tests for checking Schur()
75    
76            * inst/test-tools.R (isOrthogonal): new function; also file restructured
77    
78    2008-01-22  Martin Maechler  <maechler@stat.math.ethz.ch>
79    
80            * R/ngTMatrix.R: allow as(<numeric matrix>, "ngTMatrix") and hence
81            coercion to "nMatrix" and "pMatrix"
82    
83            * R/AllClass.R: "Schur" class;  "number" class union
84            * man/number-class.Rd:
85            * man/Schur-class.Rd:
86    
87            * R/eigen.R (.dgeSchur): utility, and return "Schur" class
88            (.simpleSchur): Schur() method for diagonal matrices
89            (.triSchur):    Schur() method for triangular matrices
90            (Schur.sym):    Schur() for symmetric matrices {building on eigen()}.
91    
92    
93    2008-01-21  Martin Maechler  <maechler@stat.math.ethz.ch>
94    
95            * src/dgCMatrix.c (dgCMatrix_QR): set @Dim slot (as per doc)
96    
97  2008-01-15  Martin Maechler  <maechler@stat.math.ethz.ch>  2008-01-15  Martin Maechler  <maechler@stat.math.ethz.ch>
98    
99          * R/CHMfactor.R (solve): method for b="numeric", but also b="ANY"          * R/CHMfactor.R (solve): method for b="numeric", but also b="ANY"
