4    
5            * R/diagMatrix.R (Ops): fix newly introduce bug in <.di> o <numeric>
6    
7            * inst/test-tools.R (isValid): new utility, used much in
8            * tests/simple.R:
9    
10            * man/BunchKaufman-methods.Rd: added too
11

25    
26            * src/dsCMatrix.c (dsCMatrix_LDL_D): cleanup, also using
27            internal_chm_factor().
28    
29            * R/AllGeneric.R: do *not* define a "chol" generic
30                    (but rather use the implicit one *without* making pivot
31                    part of the signature)
32            * R/*.R: drop the 'pivot' from chol's signature and make
33                    'pivot=FALSE' a default argument of method definitions.
34    
35            * .Rbuildignore: add 'wrld_1deg': I.e. do not put it into released
36            version of Matrix

44    
45            * R/diagMatrix.R (.symDiagonal): newly exported utility.
46    
47            * R/diagMatrix.R (Ops): <diag> * <numeric> should not become dgeMatrix!
48

52    2008-03-17  Martin Maechler  <maechler@stat.math.ethz.ch>
53    
54            * src/dsCMatrix.c (dsCMatrix_LDL_D): even faster utility with same
55            functionality; barely tested in
56            * tests/factorizing.R
57    
58            * src/Csparse.c (diag_tC): new functionality to enable faster
59            determinant(<dsCMatrix>, .) in

74    2008-03-14  Martin Maechler  <maechler@stat.math.ethz.ch>
75

94    
95            * src/dgeMatrix.c (dgeMatrix_exp): fix the octave-origin bug in the
96            back-permutation of the matrix exponential.
97    
98            * tests/matr-exp.R: test the fix (for an example where expm() was wrong).
99    
100            * DESCRIPTION (Date,Version): ready to release 0.999375-5

116            * src/Csparse.c (Csparse_Csparse_crossprod, Csparse_Csparse_prod):
117            make use of chm_diagN2U() and hence now preserve triangularity and
118            unit-triangularity.
119
