1    2008-03-22  Martin Maechler  <maechler@stat.math.ethz.ch>
2    
3            * src/dsCMatrix.c (dsCMatrix_LDL_D): cleanup, also using
4            internal_chm_factor().
5    
6            * R/AllGeneric.R: do *not* define a "chol" generic
7                    (but rather use the implicit one *without* making pivot
8                    part of the signature)
9            * R/*.R: drop the 'pivot' from chol's signature and make
10                    'pivot=FALSE' a default argument of method definitions.
11    
12            * .Rbuildignore: add 'wrld_1deg': I.e. do not put it into released
13            version of Matrix
14    
15    2008-03-18  Martin Maechler  <maechler@stat.math.ethz.ch>
16    
17            * R/Tsparse.R (.T.2.n): drop 0's before coercion to "nMatrix"
18    
19            * R/sparseMatrix.R (is.na): new simple method
20            * R/denseMatrix.R (is.na): ditto.
21    
22            * R/diagMatrix.R (.symDiagonal): newly exported utility.
23    
24            * R/diagMatrix.R (Ops): <diag> * <numeric> should not become dgeMatrix!
25    
26            * src/UFsparse_download.sh: -->
27            * src/CHOLMOD/: update to CHOLMOD version 1.6 (Nov.2007)
28    
29    2008-03-17  Martin Maechler  <maechler@stat.math.ethz.ch>
30    
31            * src/dsCMatrix.c (dsCMatrix_LDL_D): even faster utility with same
32            functionality; barely tested in
33            * tests/factorizing.R
34    
35            * src/Csparse.c (diag_tC): new functionality to enable faster
36            determinant(<dsCMatrix>, .) in
37            * R/dsCMatrix.R
38    
39    2008-03-17 18:53  Douglas Bates <bates@stat.wisc.edu>
40    
41            * R/CHMfactor.R, inst/include/Matrix.h, inst/include/Matrix_stubs.c,
42              src/CHMfactor.c, src/CHMfactor.h,
43              man/CHMfactor-class.Rd, src/init.c, tests/factorizing.R:
44              Log-determinant of the parent matrix from a CHMfactor object as
45              chm_factor_ldetL2; documentation and support
46    
47    2008-03-15  Martin Maechler  <maechler@stat.math.ethz.ch>
48    
49            * R/dsCMatrix.R: enable determinant(<dsCMatrix>, .) via chol(.)
50    
51    2008-03-14  Martin Maechler  <maechler@stat.math.ethz.ch>
52    
53            * R/dsCMatrix.R: setAs(., "dsCMatrix") but with a deprecation
54            warning.
55    
56    2008-03-13  Martin Maechler  <maechler@stat.math.ethz.ch>
57    
58            * DESCRIPTION (Version, Date): bug-fix release 0.999375-6
59    
60            * R/diagMatrix.R (diag2tT.u): utility to be smarter in
61              <diagonal> o <sparse_triangular>
62              setAs(., "nMatrix") added.
63    
64            * R/diagMatrix.R (Diagonal): Diagonal(4, x=3) now works too
65    
66            * R/Auxiliaries.R (.diagU2N): more careful coercion in 2 steps
67                    new argument 'checkDense = FALSE'.
68    
69    
70    2008-03-07  Martin Maechler  <maechler@stat.math.ethz.ch>
71    
72            * src/dgeMatrix.c (dgeMatrix_exp): fix the octave-origin bug in the
73            back-permutation of the matrix exponential.
74    
75            * tests/matr-exp.R: test the fix (for an example where expm() was wrong).
76    
77            * DESCRIPTION (Date,Version): ready to release 0.999375-5
78    
79            * tests/simple.R: testing diagN2U
80    
81    2008-03-06  Martin Maechler  <maechler@stat.math.ethz.ch>
82    
83            * R/Auxiliaries.R (diagN2U): interface to
84    
85            * src/Csparse.c (Csparse_diagN2U): .Call()able SEXP version of chm_diagN2U()
86    
87            * tests/matprod.R: test for triangularity preserving <dtC> %*% <dtC>
88    
89  2008-03-05  Martin Maechler  <maechler@stat.math.ethz.ch>  2008-03-05  Martin Maechler  <maechler@stat.math.ethz.ch>
90    
91            * src/chm_common.c (chm_diagN2U): new utility.
92    
93            * src/Csparse.c (Csparse_Csparse_crossprod, Csparse_Csparse_prod):
94            make use of chm_diagN2U() and hence now preserve triangularity and
95            unit-triangularity.
96    
97          * DESCRIPTION (LicenseDetails): new; such that 'License:' becomes "canonical"          * DESCRIPTION (LicenseDetails): new; such that 'License:' becomes "canonical"
