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() !!

30            * R/Auxiliaries.R (.diagU2N): make use of new Tsparse_diagU2N

38    
39            * R/Auxiliaries.R (as_Csparse2): drop this, replacing by

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()

58    
59            * R/ddenseMatrix.R (.trilDense,.triuDense, .bandDense):
60              now for "denseMatrix" (instead of just "ddense*"); much
61              simplified setMethod()s for these.

63            * src/dense.c (dense_to_symmetric): generalized from ddense_*
64

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"

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

106            * R/Auxiliaries.R (non0.i): take out of non0ind
107    
108            * R/ddenseMatrix.R (.trilDense, .triuDense, .bandDense):

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

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.

151    
152            * R/ngTMatrix.R: allow as(<numeric matrix>, "ngTMatrix") and hence
153            coercion to "nMatrix" and "pMatrix"
154
