# Line 1  Line 1 
1    2007-01-22  Martin Maechler  <maechler@stat.math.ethz.ch>
2    
3            * R/triangularMatrix.R: new file; simple triu() and tril() methods.
4    
5            * R/Ops.R ("Logic"): and other "Ops", many updates
6    
7    2007-01-18  Martin Maechler  <maechler@stat.math.ethz.ch>
8    
9            * src/Mutils.h (SET_DimNames): new utility
10    
11            * R/Auxiliaries.R (nnzero): improved and now exported via
12    
13            * NAMESPACE: + nnzero(); length() == prod(dim(.)) method for all "Matrix" objects
14    
15    2007-01-17  Martin Maechler  <maechler@stat.math.ethz.ch>
16    
17            * R/diagMatrix.R (!): fix typo.
18    
19    2007-01-16  Martin Maechler  <maechler@stat.math.ethz.ch>
20    
21            * R/Auxiliaries.R (as_Csparse): and quite a few others:
22                    allow to pass class definition --> speedup
23            * R/sparseMatrix.R: apply the above
24    
25            * R/Csparse.R: coercion Csparse* to dense* now preserves shape properties.
26    
27            * src/Mutils.h (mMatrix_as_geMatrix): new, based on
28            * src/Mutils.c (dup_mMatrix_as_geMatrix): new; generalization of
29            old dup_mMatrix_as_dgeMatrix), eliminating a long-standing "FIXME".
30    
31            * src/dense.c (dense_to_Csparse): use new mMatrix_as_geMatrix()
32    
33            * R/denseMatrix.R (.dense2C): based on dense_to_Csparse: name it,
34            and use it for "sparse*" as well, since it's faster than the
35            as_Csparse(.) way.
36    
37    2007-01-15  Martin Maechler  <maechler@stat.math.ethz.ch>
38    
39            * R/Ops.R ("Logic"): more methods, notably an  <lgC> o <lgC> one.
40    
41    2007-01-12  Martin Maechler  <maechler@stat.math.ethz.ch>
42    
43            * R/Tsparse.R (.TM.repl.i.2col): new internal function to be used
44            as method for   M[ ij ] <- v
45            * R/Csparse.R:: go via Tsparse for "M[ij] <- v"
46    
47            * R/Ops.R: "Compare" for (C|R)sparse: need pointer slot for all
48            FALSE answer
49    
50            * R/Csparse.R (replCmat): fix the "all non-zero" case with reordering
51            * tests/indexing.R: test it, and some of the above
52    
53    2007-01-05  Martin Maechler  <maechler@stat.math.ethz.ch>
54    
55            * R/Auxiliaries.R (is_duplicatedT): new utility
56    
57  2007-01-05  Douglas Bates  <bates@stat.wisc.edu>  2007-01-05  Douglas Bates  <bates@stat.wisc.edu>
58    
59          * src/init.c (R_init_Matrix): export cholmod_scale          * src/init.c (R_init_Matrix): export cholmod_scale
60    
61    2006-12-30  Martin Maechler  <maechler@stat.math.ethz.ch>
62    
63            * R/zzz.R (tmp): for R >= 2.5.0, extend formals of our
64            base::as.matrix to (x, ...)
65    
66  2006-12-28  Martin Maechler  <maechler@stat.math.ethz.ch>  2006-12-28  Martin Maechler  <maechler@stat.math.ethz.ch>
67    
68          * R/Ops.R ("Arith" etc): move almost all "Ops" methods to new R          * R/Ops.R ("Arith" etc): move almost all "Ops" methods to new R
