1    2008-03-04  Martin Maechler  <maechler@stat.math.ethz.ch>
2    
3            * R/diagMatrix.R (subDiag): fix when x[..] became a vector
4    
5            * src/Tsparse.c (Tsparse_diagU2N): new utility, necessary for e.g.
6            * src/Csparse.c (Csparse_crossprod): use [CT]sparse_diagU2N() !!
7    
8            * R/Auxiliaries.R (.diagU2N): make use of new Tsparse_diagU2N
9    
10            * R/Ops.R ("-" (<sparseMatrix>)): use diagU2N()
11    
12            * src/chm_common.c (AS_CHM_FINISH): add note about problem
13            for triangular (diag = "U").
14    
15    2008-02-21  Martin Maechler  <maechler@stat.math.ethz.ch>
16    
17            * R/Auxiliaries.R (as_Csparse2): drop this, replacing by
18            * R/bind.R:  .Call(dense_to_Csparse, *)
19    
20    2008-02-20  Martin Maechler  <maechler@stat.math.ethz.ch>
21    
22            * R/Matrix.R (Matrix): no longer use coercions to specific classes
23                    (since we are discouraging them in user code).
24    
25            * tests/*.R: also replaces coercions to specific classes by
26            coercions to super classes.
27    
28            * R/denseMatrix.R (.dense2C): simplified by using forceSymmetric()
29    
30    
31    2008-02-19  Martin Maechler  <maechler@stat.math.ethz.ch>
32    
33            * man/CAex.Rd: example: coerce to symmetric*, not dsC*
34    
35            * src/dense.c (dense_band): generalized from ddense_band
36    
37            * R/ddenseMatrix.R (.trilDense,.triuDense, .bandDense):
38              now for "denseMatrix" (instead of just "ddense*"); much
39              simplified setMethod()s for these.
40    
41            * src/dense.c (dense_to_symmetric): generalized from ddense_*
42    
43    2008-02-18  Martin Maechler  <maechler@stat.math.ethz.ch>
44    
45            * R/AllGeneric.R: forceSymmetric() generic: fast no-checking
46            version of as(*, "symmetricMatric").
47    
48            * src/dense.c (ddense_to_symmetric): add 'symm_test' argument, and
49            * R/symmetricMatrix.R: set it TRUE in coercion to "symmetricMatrix"
50    
51    2008-02-16  Martin Maechler  <maechler@stat.math.ethz.ch>
52    
53            * R/Matrix.R (subset.ij): utility, as first step to faster
54               M [ <ij-matrix> ] indexing.
55    
56            * R/Matrix.R (.M.sub.i.logical): M[ <logical> ] : try better.
57    
58            * src/dense.c (ddense_symmpart, ddense_skewpart): new functions
59            for more efficient symmpart() and skewpart() methods.
60    
61            * src/Mutils.c (equal_string_vectors): utility
62    
63            * src/dense.c (ddense_to_symmetric): new function used in
64    
65            * R/symmetricMatrix.R: setAs(., "symmetricMatrix")
66    
67            * R/sparseMatrix.R, et_al (isSymmetric): add '...' to formals, in
68            order to match the generic (and evade .local(..)).
69    
70            * R/dsCMatrix.R: dgC -> dsC: use C code!
71    
72            * NAMESPACE, R/AllGeneric.R (symmpart, skewpart): new functions
73            as per TODO
74    
75            * R/Auxiliaries.R (setZero, all0Matrix): new utilities
76    
77            * R/symmetricMatrix.R: obvious symmpart(), skewpart() methods
78    
79    
80    2008-02-15  Martin Maechler  <maechler@stat.math.ethz.ch>
81    
82            * R/Ops.R (.Arith.Csparse): use diagU2N when needed in triangular
83    
84            * R/Auxiliaries.R (non0.i): take out of non0ind
85    
86            * R/ddenseMatrix.R (.trilDense, .triuDense, .bandDense):
87            make tril(), triu(), band() work for "matrix" and all "dense*"
88    
89            * R/triangularMatrix.R (.tri[lu].tr): need .diagU2N(*)
90            * tests/simple.R: test the fix above
91    
92            * R/sparseMatrix.R ([): simplification: no coerce to <general>
93                    before we use as(., <Tsparse>)[...] anyway
94    
95            * R/Rsparse.R (.viaC.to.R): mostly instead of .viaC.to.dgR()
96    
97            * R/triangularMatrix.R (isTriangular): methods for all subclasses
98            instead of "triangularMatrix" -- just to disambiguate
99    
100    2008-02-14  Martin Maechler  <maechler@stat.math.ethz.ch>
101    
102            * tests/Class+Meth.R (dotestMat): add m[FALSE, FALSE] { <-> TODO}
103            * tests/indexing.R: example that fails above
104    
105    2008-01-26  Martin Maechler  <maechler@stat.math.ethz.ch>
106    
107            * R/Matrix.R (.M.sub.i.2col): fix for logical matrix indexing
108            * R/Tsparse.R (.TM.sub.i.2col, .TM.repl.i.2col): ditto;
109                    now, M[lower.tri(M)] and  M[lower.tri(M)] <- v  work better
110    
111            * src/Tsparse.c (Tsparse_to_tCsparse): new fast utility.
112            * src/Tsparse.h, init.c: ditto
113            * R/Auxiliaries.R (isTriT): new; faster than going via Csparse
114                 both isTriC() and isTriT() now return TRUE with "kind" or FALSE.
115            * R/sparseMatrix.R (isTriangular): hence simplified
116    
117    2008-01-24  Martin Maechler  <maechler@stat.math.ethz.ch>
118    
119            * R/Ops.R (.Arith.Csparse): new utility factored out of former
120              <dgC> o <dgC>, extended for triangular and also used in  <dtC> o <dtC>.

123

128    2008-01-22  Martin Maechler  <maechler@stat.math.ethz.ch>
129    
130            * R/ngTMatrix.R: allow as(<numeric matrix>, "ngTMatrix") and hence
131            coercion to "nMatrix" and "pMatrix"
132    
133            * R/AllClass.R: "Schur" class;  "number" class union
134            * man/number-class.Rd:
135            * man/Schur-class.Rd:
136    
137            * R/eigen.R (.dgeSchur): utility, and return "Schur" class
138            (.simpleSchur): Schur() method for diagonal matrices
139            (.triSchur):    Schur() method for triangular matrices
140            (Schur.sym):    Schur() for symmetric matrices {building on eigen()}.

143    2008-01-21  Martin Maechler  <maechler@stat.math.ethz.ch>
144    
145            * src/dgCMatrix.c (dgCMatrix_QR): set @Dim slot (as per doc)
146    
147  2008-01-15  Martin Maechler  <maechler@stat.math.ethz.ch>  2008-01-15  Martin Maechler  <maechler@stat.math.ethz.ch>
148    
149          * R/CHMfactor.R (solve): method for b="numeric", but also b="ANY"          * R/CHMfactor.R (solve): method for b="numeric", but also b="ANY"
