2    
3            * src/dsCMatrix.c (dsCMatrix_LDL_D): even faster utility with same
4            functionality; barely tested in
5            * tests/factorizing.R
6    
7            * src/Csparse.c (diag_tC): new functionality to enable faster
8            determinant(<dsCMatrix>, .) in
9            * R/dsCMatrix.R
10

12    
13            * R/CHMfactor.R, inst/include/Matrix.h, inst/include/Matrix_stubs.c,
14              src/CHMfactor.c, src/CHMfactor.h,
15              man/CHMfactor-class.Rd, src/init.c, tests/factorizing.R:
16              Log-determinant of the parent matrix from a CHMfactor object as
17              chm_factor_ldetL2; documentation and support
18    
19    2008-03-15  Martin Maechler  <maechler@stat.math.ethz.ch>
20    
21            * R/dsCMatrix.R: enable determinant(<dsCMatrix>, .) via chol(.)
22    
23    2008-03-14  Martin Maechler  <maechler@stat.math.ethz.ch>
24    
25            * R/dsCMatrix.R: setAs(., "dsCMatrix") but with a deprecation
26            warning.
27

29    
30            * DESCRIPTION (Version, Date): bug-fix release 0.999375-6
31    
32            * R/diagMatrix.R (diag2tT.u): utility to be smarter in
33              <diagonal> o <sparse_triangular>
34              setAs(., "nMatrix") added.
35    
36            * R/diagMatrix.R (Diagonal): Diagonal(4, x=3) now works too
37    
38            * R/Auxiliaries.R (.diagU2N): more careful coercion in 2 steps
39                    new argument 'checkDense = FALSE'.

41    
42    2008-03-07  Martin Maechler  <maechler@stat.math.ethz.ch>
43    
44            * src/dgeMatrix.c (dgeMatrix_exp): fix the octave-origin bug in the
45            back-permutation of the matrix exponential.
46    
47            * tests/matr-exp.R: test the fix (for an example where expm() was wrong).
48    
49            * DESCRIPTION (Date,Version): ready to release 0.999375-5
50    
51            * tests/simple.R: testing diagN2U
52    
53    2008-03-06  Martin Maechler  <maechler@stat.math.ethz.ch>
54    
55            * R/Auxiliaries.R (diagN2U): interface to
56    
57            * src/Csparse.c (Csparse_diagN2U): .Call()able SEXP version of chm_diagN2U()
58    
59            * tests/matprod.R: test for triangularity preserving <dtC> %*% <dtC>

62    
63            * src/chm_common.c (chm_diagN2U): new utility.
64    
65            * src/Csparse.c (Csparse_Csparse_crossprod, Csparse_Csparse_prod):
66            make use of chm_diagN2U() and hence now preserve triangularity and
67            unit-triangularity.
68    
69          * DESCRIPTION (LicenseDetails): new; such that 'License:' becomes "canonical"          * DESCRIPTION (LicenseDetails): new; such that 'License:' becomes "canonical"
