2    
3            * DESCRIPTION (Version): 0.9975-10 to upload
4    
5            * R/Rsparse.R (.R.2.C): R-level workaround since C-level
6            R_to_CMatrix segfaults on one platform.
7    
8    2007-02-01  Martin Maechler <maechler@stat.math.ethz.ch>
9    
10            * src/init.c: export the CHM...._validate() placeholders, since
11            they *are* called.
12    
13            * tests/Class+Meth.R (classCanCoerce): and starting to test
14            all as(<from>, <to>)
15    
16    2007-01-30  Martin Maechler  <maechler@stat.math.ethz.ch>
17    
18            * R/Tsparse.R ([): more care when subsetting triangular Tsparse

32            * tests/Class+Meth.R:
33    
34            * R/Ops.R (Compare): tweak for case with NA
35            * tests/simpl.R: hence another 'FIXME' eliminated

41    
42            * tests/Class+Meth.R (tstMatrixClass): now testing diag(), nnzero(),
43              and more of "!", "&", "|", all, any; coercions
44    
45            * R/Rsparse.R: many coercions (which enable quite a few other
46            methods), thanks to enhancements in
47            * src/dgCMatrix.c (R_to_CMatrix): new, and
48            * src/dgCMatrix.c (compressed_to_TMatrix): now for (d,l,n) ,
49            symmetric & triangular and ..RMatrix objects.
50    
51            * src/TMatrix_as.c (Matrix_T_as_DENSE,Matrix_T_as_GENERAL):
52            renamed file from src/dsTMatrix.c;
53            now dealing with symmetric and triangular Tsparse coercions, both
54            to dense and general.

56    2007-01-27  Martin Maechler  <maechler@stat.math.ethz.ch>
57    
58            * src/dsTMatrix.c: has now "l" and "n" methods besides the "d" ones.

63    2007-01-26  Martin Maechler  <maechler@stat.math.ethz.ch>
64    
65            * R/Matrix.R ([<-): for M[] <- value: fix length

77    
78    2007-01-18  Martin Maechler  <maechler@stat.math.ethz.ch>
79    
80            * src/Mutils.h (SET_DimNames): new utility
81    
82            * R/Auxiliaries.R (nnzero): improved and now exported via

89    
90    2007-01-16  Martin Maechler  <maechler@stat.math.ethz.ch>
91    
92            * R/Auxiliaries.R (as_Csparse): and quite a few others:
93                    allow to pass class definition --> speedup
94            * R/sparseMatrix.R: apply the above
95    
96            * R/Csparse.R: coercion Csparse* to dense* now preserves shape properties.
97    
98            * src/Mutils.h (mMatrix_as_geMatrix): new, based on
99            * src/Mutils.c (dup_mMatrix_as_geMatrix): new; generalization of

101    
102            * src/dense.c (dense_to_Csparse): use new mMatrix_as_geMatrix()
103    
104            * R/denseMatrix.R (.dense2C): based on dense_to_Csparse: name it,
105            and use it for "sparse*" as well, since it's faster than the
106            as_Csparse(.) way.
107    
108    2007-01-15  Martin Maechler  <maechler@stat.math.ethz.ch>

115            as method for   M[ ij ] <- v
116            * R/Csparse.R:: go via Tsparse for "M[ij] <- v"
117    
118            * R/Ops.R: "Compare" for (C|R)sparse: need pointer slot for all
119            FALSE answer
120    
121            * R/Csparse.R (replCmat): fix the "all non-zero" case with reordering
122            * tests/indexing.R: test it, and some of the above

137    2006-12-28  Martin Maechler  <maechler@stat.math.ethz.ch>
138    
139            * R/Ops.R ("Arith" etc): move almost all "Ops" methods to new R
140            file; start using "Logic", hence
141    
142            * DESCRIPTION (Depends): R >= 2.4.1 (since we want "Logic")
143            * NAMESPACE: import and export "Logic"
144

231            to LL before converting to a sparse matrix. (The LDL form can be
232            converted to a sparse matrix but it is implicitly a unit

234
