3            * DESCRIPTION (Date,Version): ready to release 0.999375-5
4

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

40    
41            * R/Auxiliaries.R (as_Csparse2): drop this, replacing by
42            * R/bind.R:  .Call(dense_to_Csparse, *)
43    
44    2008-02-20  Martin Maechler  <maechler@stat.math.ethz.ch>
45    
46            * R/Matrix.R (Matrix): no longer use coercions to specific classes
47                    (since we are discouraging them in user code).
48    
49            * tests/*.R: also replaces coercions to specific classes by
50            coercions to super classes.
51    
52            * R/denseMatrix.R (.dense2C): simplified by using forceSymmetric()
53

60    
61            * R/ddenseMatrix.R (.trilDense,.triuDense, .bandDense):
62              now for "denseMatrix" (instead of just "ddense*"); much
63              simplified setMethod()s for these.
64    
65            * src/dense.c (dense_to_symmetric): generalized from ddense_*
66    
67    2008-02-18  Martin Maechler  <maechler@stat.math.ethz.ch>
68    
69            * R/AllGeneric.R: forceSymmetric() generic: fast no-checking
70            version of as(*, "symmetricMatric").
71    
72            * src/dense.c (ddense_to_symmetric): add 'symm_test' argument, and
73            * R/symmetricMatrix.R: set it TRUE in coercion to "symmetricMatrix"
74    
75    2008-02-16  Martin Maechler  <maechler@stat.math.ethz.ch>
76    
77            * R/Matrix.R (subset.ij): utility, as first step to faster
78               M [ <ij-matrix> ] indexing.
79    
80            * R/Matrix.R (.M.sub.i.logical): M[ <logical> ] : try better.
81

86    
87            * src/dense.c (ddense_to_symmetric): new function used in
88    
89            * R/symmetricMatrix.R: setAs(., "symmetricMatrix")
90    
91            * R/sparseMatrix.R, et_al (isSymmetric): add '...' to formals, in
92            order to match the generic (and evade .local(..)).
93    
94            * R/dsCMatrix.R: dgC -> dsC: use C code!
95    
96            * NAMESPACE, R/AllGeneric.R (symmpart, skewpart): new functions
97            as per TODO
98    
99            * R/Auxiliaries.R (setZero, all0Matrix): new utilities
100    
101            * R/symmetricMatrix.R: obvious symmpart(), skewpart() methods

107    
108            * R/Auxiliaries.R (non0.i): take out of non0ind
109    
110            * R/ddenseMatrix.R (.trilDense, .triuDense, .bandDense):
111            make tril(), triu(), band() work for "matrix" and all "dense*"
112    
113            * R/triangularMatrix.R (.tri[lu].tr): need .diagU2N(*)
114            * tests/simple.R: test the fix above
115    
116            * R/sparseMatrix.R ([): simplification: no coerce to <general>
117                    before we use as(., <Tsparse>)[...] anyway
118    
119            * R/Rsparse.R (.viaC.to.R): mostly instead of .viaC.to.dgR()
120    
121            * R/triangularMatrix.R (isTriangular): methods for all subclasses
122            instead of "triangularMatrix" -- just to disambiguate
123    
124    2008-02-14  Martin Maechler  <maechler@stat.math.ethz.ch>
125    
126            * tests/Class+Meth.R (dotestMat): add m[FALSE, FALSE] { <-> TODO}

132            * R/Tsparse.R (.TM.sub.i.2col, .TM.repl.i.2col): ditto;
133                    now, M[lower.tri(M)] and  M[lower.tri(M)] <- v  work better
134    
135            * src/Tsparse.c (Tsparse_to_tCsparse): new fast utility.
136            * src/Tsparse.h, init.c: ditto
137            * R/Auxiliaries.R (isTriT): new; faster than going via Csparse
138                 both isTriC() and isTriT() now return TRUE with "kind" or FALSE.
139            * R/sparseMatrix.R (isTriangular): hence simplified
140

142    
143            * R/Ops.R (.Arith.Csparse): new utility factored out of former

153    
154            * R/ngTMatrix.R: allow as(<numeric matrix>, "ngTMatrix") and hence
155            coercion to "nMatrix" and "pMatrix"
156    
157            * R/AllClass.R: "Schur" class;  "number" class union
158            * man/number-class.Rd:
159            * man/Schur-class.Rd:
160    
161            * R/eigen.R (.dgeSchur): utility, and return "Schur" class

172    
173          * R/CHMfactor.R (solve): method for b="numeric", but also b="ANY"          * R/CHMfactor.R (solve): method for b="numeric", but also b="ANY"
