1 : mmaechler 2239 2008-07-28 Martin Maechler <maechler@stat.math.ethz.ch>
2 :    
3 :     * R/AllClass.R (diagonalMatrix): extend "sparseMatrix" instead of
4 :     "denseMatrix". This renders "scarceMatrix" dispensable and
5 :     invalidates part of MM's presentations on "space of Matrix
6 :     classes", but seems cleaner overall.
7 :    
8 :     * R/diagMatrix.R, etc: eliminate "scarceMatrix", replacing it by
9 :     "sparseMatrix" in method signatures;
10 :     further, instead of coercing to "sparseMatrix", coerce to
11 :     "TsparseMatrix" now.
12 :    
13 :     2008-07-26 Martin Maechler <maechler@stat.math.ethz.ch>
14 :    
15 :     * src/dgCMatrix.c (dgCMatrix_qrsol): allow third argument 'order' in
16 :     .Call(.)
17 :     * R/sparseMatrix.R (lm.fit.sparse), src/dgCMatrix.h, src/init.c: ditto
18 :    
19 : mmaechler 2237 2008-07-24 Martin Maechler <maechler@stat.math.ethz.ch>
20 :    
21 :     * R/dgeMatrix.R: need solve(<dge>, <sparse>) against infinite
22 :     recursion in new test in
23 :     * tests/matprod.R: testing the above and another solve() case, below
24 :    
25 :     * R/sparseMatrix.R (lm.fit.sparse): slightly more efficient for
26 :     e.g. triangular 'x'.
27 :    
28 :     * src/dgCMatrix.c (dgCMatrix_qrsol): use AS_CSP() hence allowing dtC*
29 :     * src/dgCMatrix.c (dgCMatrix_cholsol): use AS_CHM_SP() to work
30 :     correctly with unit-triangular x
31 :    
32 :     * src/dsCMatrix.c (dsCMatrix_Csparse_solve): use AS_CHM_SP()
33 :     instead of not checking diagU.
34 :    
35 :     * R/diagMatrix.R, R/Auxiliaries.R: tweaks to allow later
36 :     experiments where diagonalMatrix would extend sparse*.
37 :    
38 :    
39 : mmaechler 2235 2008-07-23 Martin Maechler <maechler@stat.math.ethz.ch>
40 :    
41 : mmaechler 2236 * src/dgCMatrix.c (compressed_non_0_ij): for nnzero(), use
42 :     "x@p[ncol(x)]" instead of length(x@i).
43 :     * R/Auxiliaries.R (nnzero): ditto
44 :    
45 :     * src/chm_common.c (as_cholmod_sparse): Do not use LENGTH(islot)
46 :     since that fails for over-allocated i.
47 :    
48 :     * tests/validObj.R: more testing of over-allocated (i,x) slots
49 :    
50 :     2008-07-23 Martin Maechler <maechler@stat.math.ethz.ch>

55 :     validObject() continues sort the columns if needed.
56 :    
57 : mmaechler 2236 * tests/validObj.R: now tests that more thoroughly, and
58 :     * man/CsparseMatrix-class.Rd: documents it.
