2    
3            * DESCRIPTION (LicenseDetails): new; such that 'License:' becomes "canonical"
4    
5    2008-03-04  Martin Maechler  <maechler@stat.math.ethz.ch>
6    
7            * R/diagMatrix.R (subDiag): fix when x[..] became a vector
8    
9            * src/Tsparse.c (Tsparse_diagU2N): new utility, necessary for e.g.
10            * src/Csparse.c (Csparse_crossprod): use [CT]sparse_diagU2N() !!
11    
12            * R/Auxiliaries.R (.diagU2N): make use of new Tsparse_diagU2N
13    
14            * R/Ops.R ("-" (<sparseMatrix>)): use diagU2N()
15    
16            * src/chm_common.c (AS_CHM_FINISH): add note about problem
17            for triangular (diag = "U").
18    
19    2008-02-21  Martin Maechler  <maechler@stat.math.ethz.ch>
20    
21            * R/Auxiliaries.R (as_Csparse2): drop this, replacing by
22            * R/bind.R:  .Call(dense_to_Csparse, *)
23    
24    2008-02-20  Martin Maechler  <maechler@stat.math.ethz.ch>
25    
26            * R/Matrix.R (Matrix): no longer use coercions to specific classes
27                    (since we are discouraging them in user code).
28    
29            * tests/*.R: also replaces coercions to specific classes by
30            coercions to super classes.
31    
32            * R/denseMatrix.R (.dense2C): simplified by using forceSymmetric()
33    
34    
35    2008-02-19  Martin Maechler  <maechler@stat.math.ethz.ch>

40    
41            * R/ddenseMatrix.R (.trilDense,.triuDense, .bandDense):
42              now for "denseMatrix" (instead of just "ddense*"); much
43              simplified setMethod()s for these.

46

48    
49            * R/AllGeneric.R: forceSymmetric() generic: fast no-checking
50            version of as(*, "symmetricMatric").

52            * src/dense.c (ddense_to_symmetric): add 'symm_test' argument, and
53            * R/symmetricMatrix.R: set it TRUE in coercion to "symmetricMatrix"
54    
55    2008-02-16  Martin Maechler  <maechler@stat.math.ethz.ch>
56    
57            * R/Matrix.R (subset.ij): utility, as first step to faster
58               M [ <ij-matrix> ] indexing.
59

66    
67            * src/dense.c (ddense_to_symmetric): new function used in
68    
69            * R/symmetricMatrix.R: setAs(., "symmetricMatrix")
70    
71            * R/sparseMatrix.R, et_al (isSymmetric): add '...' to formals, in
72            order to match the generic (and evade .local(..)).
73    
74            * R/dsCMatrix.R: dgC -> dsC: use C code!
75    
76            * NAMESPACE, R/AllGeneric.R (symmpart, skewpart): new functions
77            as per TODO

89    
90            * R/ddenseMatrix.R (.trilDense, .triuDense, .bandDense):
91            make tril(), triu(), band() work for "matrix" and all "dense*"

94            * tests/simple.R: test the fix above
95    
96            * R/sparseMatrix.R ([): simplification: no coerce to <general>
97                    before we use as(., <Tsparse>)[...] anyway
98    
99            * R/Rsparse.R (.viaC.to.R): mostly instead of .viaC.to.dgR()
100    
101            * R/triangularMatrix.R (isTriangular): methods for all subclasses

114    
115            * src/Tsparse.c (Tsparse_to_tCsparse): new fast utility.
116            * src/Tsparse.h, init.c: ditto
117            * R/Auxiliaries.R (isTriT): new; faster than going via Csparse
118                 both isTriC() and isTriT() now return TRUE with "kind" or FALSE.

135            coercion to "nMatrix" and "pMatrix"
136
