1    2008-03-18  Martin Maechler  <maechler@stat.math.ethz.ch>
2    
3            * R/Tsparse.R (.T.2.n): drop 0's before coercion to "nMatrix"
4    
5            * R/sparseMatrix.R (is.na): new simple method
6            * R/denseMatrix.R (is.na): ditto.
7    
8            * R/diagMatrix.R (.symDiagonal): newly exported utility.
9    
10            * R/diagMatrix.R (Ops): <diag> * <numeric> should not become dgeMatrix!
11    
12            * src/UFsparse_download.sh: -->
13            * src/CHOLMOD/: update to CHOLMOD version 1.6 (Nov.2007)
14    
15    2008-03-17  Martin Maechler  <maechler@stat.math.ethz.ch>
16    
17            * src/dsCMatrix.c (dsCMatrix_LDL_D): even faster utility with same
18            functionality; barely tested in
19            * tests/factorizing.R
20    
21            * src/Csparse.c (diag_tC): new functionality to enable faster
22            determinant(<dsCMatrix>, .) in
23            * R/dsCMatrix.R
24    
25    2008-03-17 18:53  Douglas Bates <bates@stat.wisc.edu>
26    
27            * R/CHMfactor.R, inst/include/Matrix.h, inst/include/Matrix_stubs.c,
28              src/CHMfactor.c, src/CHMfactor.h,
29              man/CHMfactor-class.Rd, src/init.c, tests/factorizing.R:
30              Log-determinant of the parent matrix from a CHMfactor object as
31              chm_factor_ldetL2; documentation and support
32    
33    2008-03-15  Martin Maechler  <maechler@stat.math.ethz.ch>
34    
35            * R/dsCMatrix.R: enable determinant(<dsCMatrix>, .) via chol(.)
36    
37    2008-03-14  Martin Maechler  <maechler@stat.math.ethz.ch>
38    
39            * R/dsCMatrix.R: setAs(., "dsCMatrix") but with a deprecation
40            warning.
41    
42    2008-03-13  Martin Maechler  <maechler@stat.math.ethz.ch>
43    
44            * DESCRIPTION (Version, Date): bug-fix release 0.999375-6
45    
46            * R/diagMatrix.R (diag2tT.u): utility to be smarter in
47              <diagonal> o <sparse_triangular>
48              setAs(., "nMatrix") added.
49    
50            * R/diagMatrix.R (Diagonal): Diagonal(4, x=3) now works too
51    
52            * R/Auxiliaries.R (.diagU2N): more careful coercion in 2 steps
53                    new argument 'checkDense = FALSE'.
54    
55    
56    2008-03-07  Martin Maechler  <maechler@stat.math.ethz.ch>
57    
58            * src/dgeMatrix.c (dgeMatrix_exp): fix the octave-origin bug in the
59            back-permutation of the matrix exponential.
60    
61            * tests/matr-exp.R: test the fix (for an example where expm() was wrong).
62    
63            * DESCRIPTION (Date,Version): ready to release 0.999375-5
64    
65            * tests/simple.R: testing diagN2U
66    
67    2008-03-06  Martin Maechler  <maechler@stat.math.ethz.ch>
68    
69            * R/Auxiliaries.R (diagN2U): interface to
70    
71            * src/Csparse.c (Csparse_diagN2U): .Call()able SEXP version of chm_diagN2U()
72    
73            * tests/matprod.R: test for triangularity preserving <dtC> %*% <dtC>
74    
75  2008-03-05  Martin Maechler  <maechler@stat.math.ethz.ch>  2008-03-05  Martin Maechler  <maechler@stat.math.ethz.ch>
76    
77            * src/chm_common.c (chm_diagN2U): new utility.
78    
79            * src/Csparse.c (Csparse_Csparse_crossprod, Csparse_Csparse_prod):
80            make use of chm_diagN2U() and hence now preserve triangularity and
81            unit-triangularity.
82    
83          * DESCRIPTION (LicenseDetails): new; such that 'License:' becomes "canonical"          * DESCRIPTION (LicenseDetails): new; such that 'License:' becomes "canonical"
