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