1    2008-09-05  Martin Maechler  <maechler@stat.math.ethz.ch>
2    
3            * R/Matrix.R (solve,..): use (Matrix,ANY)... instead of (Matrix,Matrix)

22    
23            * R/Auxiliaries.R (attrSlotNames, attrSlots, attr.all_Mat): new
24            utilities, for now to be used in all.equal() methods.
25

43    
44    2008-08-25  Martin Maechler  <maechler@stat.math.ethz.ch>
45    
46            * src/dgCMatrix.c (dgCMatrix_LU): partially revert change
47            r2175 (2008-04-23) and do give an error for a singular matrix.
48            * man/lu.Rd, R/Auxiliaries.R (detSparseLU): adapt to that.
49    
50            * R/LU.R: expand( <sparseLU> )
51

55    
56    
57    2008-08-23  Douglas Bates <bates@stat.wisc.edu>
58    
59            * [r2243] R/CHMfactor.R, man/CHMfactor-class.Rd: Added expand method and
60              documentation for CHMfactor class
61            * [r2241] R/CHMfactor.R: Added trivial coercion method for CHMfactor ->
62              pMatrix
63    
64    2008-08-19  Martin Maechler  <maechler@stat.math.ethz.ch>
65    
66            * R/nsCMatrix.R (setAs(., dgTMatrix))): remove unused method
67    
68    2008-08-18  Martin Maechler  <maechler@stat.math.ethz.ch>
69    
70            * R/Ops.R (.Ops2dge.via.x, and many others): eliminate never-used
71            variable assignments {from "next version" codetools}.
72            * R/Csparse.R, R/Tsparse.R: ditto
73    
74    2008-08-17  Martin Maechler  <maechler@stat.math.ethz.ch>
75    
76            * R/sparseVector.R (sp2vec, coerce to sparseVector):
77            make sure no integer overflows happen, and use double precision
78            (n, index) where appropriate.
79    
80            * tests/Simple.R: test "large" sparse vectors.
81    
82    2008-08-14  Martin Maechler  <maechler@stat.math.ethz.ch>
83    
84            * R/AllClass.R (sparseVector): 'length' and 'i' are "numeric", not
85            just integer (allowing much longer length).
86    
87    2008-07-28  Martin Maechler  <maechler@stat.math.ethz.ch>
88    
89            * R/AllClass.R (diagonalMatrix): extend  "sparseMatrix" instead of
90            "denseMatrix".  This renders "scarceMatrix" dispensable and
91            invalidates part of MM's presentations on "space of Matrix
92            classes", but seems cleaner overall.
93    
94            * R/diagMatrix.R, etc: eliminate "scarceMatrix", replacing it by
95            "sparseMatrix" in method signatures;
96            further, instead of coercing to "sparseMatrix", coerce to
97            "TsparseMatrix" now.
98    
99    2008-07-26  Martin Maechler  <maechler@stat.math.ethz.ch>
100    
101            * src/dgCMatrix.c (dgCMatrix_qrsol): allow third argument 'order' in
102            .Call(.)
103            * R/sparseMatrix.R (lm.fit.sparse), src/dgCMatrix.h, src/init.c: ditto
104    
105    2008-07-24  Martin Maechler  <maechler@stat.math.ethz.ch>
106    
107            * R/dgeMatrix.R: need solve(<dge>, <sparse>) against infinite
108            recursion in new test in
109            * tests/matprod.R: testing the above and another solve() case, below
110    
111            * R/sparseMatrix.R (lm.fit.sparse): slightly more efficient for
112            e.g. triangular 'x'.
113    
114            * src/dgCMatrix.c (dgCMatrix_qrsol): use AS_CSP() hence allowing dtC*
115            * src/dgCMatrix.c (dgCMatrix_cholsol): use AS_CHM_SP() to work
116            correctly with unit-triangular x
117    
118            * src/dsCMatrix.c (dsCMatrix_Csparse_solve): use AS_CHM_SP()
119            instead of not checking diagU.
120    
121            * R/diagMatrix.R, R/Auxiliaries.R: tweaks to allow later
122            experiments where diagonalMatrix would extend sparse*.
123    
124    
125    2008-07-23  Martin Maechler  <maechler@stat.math.ethz.ch>
126    
127            * src/dgCMatrix.c (compressed_non_0_ij): for nnzero(), use
128            "x@p[ncol(x)]" instead of length(x@i).
129            * R/Auxiliaries.R (nnzero): ditto
130    
131            * src/chm_common.c (as_cholmod_sparse): Do not use LENGTH(islot)
132            since that fails for over-allocated i.
133    
134            * tests/validObj.R: more testing of over-allocated (i,x) slots
135    
136    2008-07-23  Martin Maechler  <maechler@stat.math.ethz.ch>
137    
138            * src/chm_common.c (as_cholmod_sparse): Add 4th argument
139            'sort_in_place' and set it to TRUE in call from
140            * src/Csparse.c (Csparse_validate): sort in place, making sure that
141            validObject() continues sort the columns if needed.
142    
143            * tests/validObj.R: now tests that more thoroughly, and
144            * man/CsparseMatrix-class.Rd: documents it.
145    
146    2008-07-22  Douglas Bates <bates@stat.wisc.edu>
147    
148            * [r2233] src/chm_common.c: sort columns more carefully in
149              as_cholmod_sparse
150            * [r2231] src/chm_common.c: check for sorted columns in
151              as_cholmod_sparse instead of assuming it
152            * [r2228] src/cs_utils.c: Use R_alloc for semi-permanent storage when
153              expanding diagonal
154

157    
158            * src/cs_utils.c (Matrix_as_cs): add check_Udiag switch
159            * src/cs_utils.h (AS_CSP & AS_CSP__): two versions
160            * src/dtCMatrix.c (dtCMatrix_sparse_solve): no longer needs
161            diagU2N().
162    
163          * R/diagMatrix.R (.sparseDiagonal): new utility, used in "old"          * R/diagMatrix.R (.sparseDiagonal): new utility, used in "old"
164          .spDiagonal() and new .trDiagonal().          .spDiagonal() and new .trDiagonal().

188    
189            * [r2220] src/dtCMatrix.c: Correct number of columns for rhs in
190              dtCMatrix_sparse_solve
191            * [r2219] src/cs_utils.c: eye->nz should be -1 for compressed column
192              storage
