1    2007-01-29  Martin Maechler  <maechler@stat.math.ethz.ch>
2    
3            * R/diagMatrix.R (solve): the obvious methods for diagonalMatrix
4            objects.
5    
6            * tests/Class+Meth.R (tstMatrixClass): now testing diag(), nnzero(),
7              and more of "!", "&", "|", all, any; coercions
8    
9            * R/Rsparse.R: many coercions (which enable quite a few other
10            methods), thanks to enhancements in
11            * src/dgCMatrix.c (R_to_CMatrix): new, and
12            * src/dgCMatrix.c (compressed_to_TMatrix): now for (d,l,n) ,
13            symmetric & triangular and ..RMatrix objects.
14    
15            * src/TMatrix_as.c (Matrix_T_as_DENSE,Matrix_T_as_GENERAL):
16            renamed file from src/dsTMatrix.c;
17            now dealing with symmetric and triangular Tsparse coercions, both
18            to dense and general.
19    
20    2007-01-27  Martin Maechler  <maechler@stat.math.ethz.ch>
21    
22            * src/dsTMatrix.c: has now "l" and "n" methods besides the "d" ones.
23    
24            * R/Ops.R (Arith): <dgCMatrix> o <numeric> now remains sparse
25            where sensible when the <numeric> is of length > 1.
26    
27    2007-01-26  Martin Maechler  <maechler@stat.math.ethz.ch>
28    
29            * R/Matrix.R ([<-): for M[] <- value: fix length
30    
31    2007-01-25  Martin Maechler  <maechler@stat.math.ethz.ch>
32    
33            * R/Auxiliaries.R (n2l_Matrix): new, to be used in
34            * R/ndenseMatrix.R: new coercions n* -> l*
35    
36    2007-01-22  Martin Maechler  <maechler@stat.math.ethz.ch>
37    
38            * R/triangularMatrix.R: new file; simple triu() and tril() methods.
39    
40            * R/Ops.R ("Logic"): and other "Ops", many updates
41    
42    2007-01-18  Martin Maechler  <maechler@stat.math.ethz.ch>
43    
44            * src/Mutils.h (SET_DimNames): new utility
45    
46            * R/Auxiliaries.R (nnzero): improved and now exported via
47    
48            * NAMESPACE: + nnzero(); length() == prod(dim(.)) method for all "Matrix" objects
49    
50    2007-01-17  Martin Maechler  <maechler@stat.math.ethz.ch>
51    
52            * R/diagMatrix.R (!): fix typo.
53    
54    2007-01-16  Martin Maechler  <maechler@stat.math.ethz.ch>
55    
56            * R/Auxiliaries.R (as_Csparse): and quite a few others:
57                    allow to pass class definition --> speedup
58            * R/sparseMatrix.R: apply the above
59    
60            * R/Csparse.R: coercion Csparse* to dense* now preserves shape properties.
61    
62            * src/Mutils.h (mMatrix_as_geMatrix): new, based on
63            * src/Mutils.c (dup_mMatrix_as_geMatrix): new; generalization of
64            old dup_mMatrix_as_dgeMatrix), eliminating a long-standing "FIXME".
65    
66            * src/dense.c (dense_to_Csparse): use new mMatrix_as_geMatrix()
67    
68            * R/denseMatrix.R (.dense2C): based on dense_to_Csparse: name it,
69            and use it for "sparse*" as well, since it's faster than the
70            as_Csparse(.) way.
71    
72    2007-01-15  Martin Maechler  <maechler@stat.math.ethz.ch>
73    
74            * R/Ops.R ("Logic"): more methods, notably an  <lgC> o <lgC> one.
75    
76    2007-01-12  Martin Maechler  <maechler@stat.math.ethz.ch>
77    
78            * R/Tsparse.R (.TM.repl.i.2col): new internal function to be used
79            as method for   M[ ij ] <- v
80            * R/Csparse.R:: go via Tsparse for "M[ij] <- v"
81    
82            * R/Ops.R: "Compare" for (C|R)sparse: need pointer slot for all
83            FALSE answer
84    
85            * R/Csparse.R (replCmat): fix the "all non-zero" case with reordering
86            * tests/indexing.R: test it, and some of the above
87    
88    2007-01-05  Martin Maechler  <maechler@stat.math.ethz.ch>

99            base::as.matrix to (x, ...)
100    
101    2006-12-28  Martin Maechler  <maechler@stat.math.ethz.ch>
102    
103            * R/Ops.R ("Arith" etc): move almost all "Ops" methods to new R
104            file; start using "Logic", hence
105    
106            * DESCRIPTION (Depends): R >= 2.4.1 (since we want "Logic")

195            to LL before converting to a sparse matrix. (The LDL form can be
196            converted to a sparse matrix but it is implicitly a unit
197            triangular matrix and a diagonal matrix overwritten on the diagonal.)
198    
199    2006-12-09  Douglas Bates  <bates@stat.wisc.edu>

209    
210          * R/diagMatrix.R (%*%): write a direct [diag o Csparse] method          * R/diagMatrix.R (%*%): write a direct [diag o Csparse] method
