4    
5    2006-11-29  Douglas Bates  <bates@stat.wisc.edu>
6    
7            * src/dgeMatrix.c (dgeMatrix_solve): Check error code from dgetri.
8            * tests/dg_Matrix.R: Add Barry Rowlingson's test of a matrix that
9            is exactly singular.

13            * DESCRIPTION (Date): updated -> release 0.9975-6
14    
15    2006-11-06  Martin Maechler  <maechler@stat.math.ethz.ch>
16    
17            * R/Csparse.R (replCmat): symmetric indexing of symmetric matrix
18            now returns symmetric.
19    
20            * R/zzz.R ("diag<-"): replace "diag<-" in base for R <= 2.4.x
21    
22            * R/Matrix.R (.M.sub.i.2col):  new, for  M[ cbind(i,j) ] indexing.
23            * R/Matrix.R (.M.repl.i.2col): new, for  M[ cbind(i,j) ] <- value
24    
25            * R/Auxiliaries.R (.type.kind): added
26    
27    2006-11-04  Martin Maechler  <maechler@stat.math.ethz.ch>
28    
29            * src/cs.[ch]: updated to CSparse Version 2.0.3 by simply
30            running src/CSparse_install.sh
31    
32            * R/denseMatrix.R: "[": keep symmetric on symmetric indexing.
33    
34    2006-11-03  Martin Maechler  <maechler@stat.math.ethz.ch>
35    
36            * src/dsCMatrix.c (dsCMatrix_Csparse_solve): new
37            * R/dsCMatrix.R (solve): "fully-sparse" using the above.
38    
39            * R/AllClass.R: "pMatrix" now also inherits from "generalMatrix"
40    
41            * tests/Class+Meth.R (tstMatrixClass): now assure
42            the (important in method programming) property :
43    
44                    ###>>  Every "Matrix" is either
45                    ###>>  "general*", "symmetric*", "triangular*" or "diagonal*"
46    
47                    (where "*" stands for "Matrix")
48    
49            * R/Auxiliaries.R (diagU2N): now .Call()s Csparse_diagU2N for <Csparse>
50    
51            * R/dMatrix.R (Compare(<dMatrix>,<dMatrix>): update and
52            * tests/validObj.R: checks for "comparison"
53    
54            * R/sparseMatrix.R ([): improved indexing for sparse;
55                    trying to keep <symmetric>[ n, n] symmmetric
56    
57            * tests/indexing.R: indexing for logical sparse now ok
58    
59    
60    2006-11-02  Martin Maechler  <maechler@stat.math.ethz.ch>
61    
62            * src/Tsparse.c: use xTsparse_validate() , and hence remove
63    
64            * src/{ltC,lsC,lgT}Matrix.[ch]: removed
65    
66    2006-11-02  Martin Maechler  <maechler@stat.math.ethz.ch>
67    
68            * R/AllClass.R (Matrix-class): check length of dimnames in validity.
69    
70            * tests/simple.R: validObject() checking the above.
71    
72            * src/dgCMatrix.c (xCMatrix_validate): new, small and simple,
73            replacing both dgCMatrix_validate and lgCM*.
74    
75            * src/Csparse.c (Csparse_dense_prod, etc): do not lose dimnames;
76            fix dimnames setting in other places.

85            * R/Auxiliaries.R (.as.dgC.0.factors):
86

90            man/CsparseMatrix-class.Rd: crossprod(<CsparseMatrix>,
91            <CsparseMatrix>) added
92

98            recursive infinitely.
99

103    
104    2006-10-28  Martin Maechler  <maechler@stat.math.ethz.ch>
105    
106            * tests/Class+Meth.R (tstMatrixClass): more: use non-trivial
107            matrix if possible; test m+m == 2*m; now test dgRMatrix.
108            * R/dgRMatrix.R (.to.dgR): a few more coercions, in order to
109            satisfy the above test.
