1    2006-11-06  Martin Maechler  <maechler@stat.math.ethz.ch>
2    
3            * R/Csparse.R (replCmat): symmetric indexing of symmetric matrix
4            now returns symmetric.
5    
6            * R/zzz.R ("diag<-"): replace "diag<-" in base for R <= 2.4.x
7    
8            * R/Matrix.R (.M.sub.i.2col):  new, for  M[ cbind(i,j) ] indexing.
9            * R/Matrix.R (.M.repl.i.2col): new, for  M[ cbind(i,j) ] <- value
10    
11            * R/Auxiliaries.R (.type.kind): added
12    
13    2006-11-04  Martin Maechler  <maechler@stat.math.ethz.ch>
14    
15            * src/cs.[ch]: updated to CSparse Version 2.0.3 by simply
16            running src/CSparse_install.sh
17    
18            * R/denseMatrix.R: "[": keep symmetric on symmetric indexing.
19    
20    2006-11-03  Martin Maechler  <maechler@stat.math.ethz.ch>
21    
22            * src/dsCMatrix.c (dsCMatrix_Csparse_solve): new
23            * R/dsCMatrix.R (solve): "fully-sparse" using the above.
24    
25            * R/AllClass.R: "pMatrix" now also inherits from "generalMatrix"
26    
27            * tests/Class+Meth.R (tstMatrixClass): now assure
28            the (important in method programming) property :
29    
30                    ###>>  Every "Matrix" is either
31                    ###>>  "general*", "symmetric*", "triangular*" or "diagonal*"
32    
33                    (where "*" stands for "Matrix")
34    
35            * R/Auxiliaries.R (diagU2N): now .Call()s Csparse_diagU2N for <Csparse>
36    
37            * R/dMatrix.R (Compare(<dMatrix>,<dMatrix>): update and
38            * tests/validObj.R: checks for "comparison"
39    
40            * R/sparseMatrix.R ([): improved indexing for sparse;
41                    trying to keep <symmetric>[ n, n] symmmetric
42    
43            * tests/indexing.R: indexing for logical sparse now ok
44    
45    
46    2006-11-02  Martin Maechler  <maechler@stat.math.ethz.ch>
47    
48            * src/Tsparse.c: use xTsparse_validate() , and hence remove
49    
50            * src/{ltC,lsC,lgT}Matrix.[ch]: removed
51    
52    2006-11-02  Martin Maechler  <maechler@stat.math.ethz.ch>
53    
54            * R/AllClass.R (Matrix-class): check length of dimnames in validity.
55    
56            * tests/simple.R: validObject() checking the above.
57    
58            * src/dgCMatrix.c (xCMatrix_validate): new, small and simple,
59            replacing both dgCMatrix_validate and lgCM*.
60    
61            * src/Csparse.c (Csparse_dense_prod, etc): do not lose dimnames;
62            fix dimnames setting in other places.
63            * src/chm_common.c (chm_dense_to_SEXP): now can pass dimnames
64    
65    2006-11-01  Martin Maechler  <maechler@stat.math.ethz.ch>
66    
67            * R/Csparse.R,src/Csparse.c, etc: tcrossprod(<CsparseM>,<CsparseM>)
68    
69            * R/sparseMatrix.R (isSymmetric): drop 'factors' slot for
70            symmetry test, via
71            * R/Auxiliaries.R (.as.dgC.0.factors):
72    
73    2006-11-01  Douglas Bates  <bates@r-project.org>
74    
75            * R/Csparse.R,src/Csparse.c,tests/matprod.R,
76            man/CsparseMatrix-class.Rd: crossprod(<CsparseMatrix>,
77            <CsparseMatrix>) added
78    
79    2006-10-30  Martin Maechler  <maechler@stat.math.ethz.ch>
80    
81            * tests/matprod.R: add a variation of Harri's example
82    
83            * R/dsparseMatrix.R: fix crossprod(<dsparse>, <dge>) to *not*
84            recursive infinitely.
85    
86            * R/dgCMatrix.R: + solve(<sparse>, <sparse>)
87    
88            * tests/indexing.R: add test for the "<" bug fixed 10-27 in R/dMatrix.R
89    
90    2006-10-28  Martin Maechler  <maechler@stat.math.ethz.ch>
91    
92            * tests/Class+Meth.R (tstMatrixClass): more: use non-trivial
93            matrix if possible; test m+m == 2*m; now test dgRMatrix.
94            * R/dgRMatrix.R (.to.dgR): a few more coercions, in order to
95            satisfy the above test.
96    
97  2006-10-27  Martin Maechler  <maechler@stat.math.ethz.ch>  2006-10-27  Martin Maechler  <maechler@stat.math.ethz.ch>
98    
99            * R/Matrix.R (Ops):  <Matrix> o <matrix>  method added
