4            back-permutation of the matrix exponential.
5    
6            * tests/matr-exp.R: test the fix (for an example where expm() was wrong).
7    
8            * DESCRIPTION (Date,Version): ready to release 0.999375-5
9

23    
24            * src/Csparse.c (Csparse_Csparse_crossprod, Csparse_Csparse_prod):

28            * DESCRIPTION (LicenseDetails): new; such that 'License:' becomes "canonical"
29

31    
32            * R/diagMatrix.R (subDiag): fix when x[..] became a vector
33    
34            * src/Tsparse.c (Tsparse_diagU2N): new utility, necessary for e.g.

49    2008-02-20  Martin Maechler  <maechler@stat.math.ethz.ch>
50    
51            * R/Matrix.R (Matrix): no longer use coercions to specific classes
52                    (since we are discouraging them in user code).

55            coercions to super classes.
56

65    
66            * R/ddenseMatrix.R (.trilDense,.triuDense, .bandDense):
67              now for "denseMatrix" (instead of just "ddense*"); much

71

73    
74            * R/AllGeneric.R: forceSymmetric() generic: fast no-checking
75            version of as(*, "symmetricMatric").
76    
77            * src/dense.c (ddense_to_symmetric): add 'symm_test' argument, and
78            * R/symmetricMatrix.R: set it TRUE in coercion to "symmetricMatrix"

93    
94            * R/symmetricMatrix.R: setAs(., "symmetricMatrix")
95    
96            * R/sparseMatrix.R, et_al (isSymmetric): add '...' to formals, in
97            order to match the generic (and evade .local(..)).
98    
99            * R/dsCMatrix.R: dgC -> dsC: use C code!
100    
101            * NAMESPACE, R/AllGeneric.R (symmpart, skewpart): new functions

112    
113            * R/Auxiliaries.R (non0.i): take out of non0ind
114    
115            * R/ddenseMatrix.R (.trilDense, .triuDense, .bandDense):

119            * tests/simple.R: test the fix above
120    
121            * R/sparseMatrix.R ([): simplification: no coerce to <general>
122                    before we use as(., <Tsparse>)[...] anyway
123    
124            * R/Rsparse.R (.viaC.to.R): mostly instead of .viaC.to.dgR()
125

137            * R/Tsparse.R (.TM.sub.i.2col, .TM.repl.i.2col): ditto;

139    
140            * src/Tsparse.c (Tsparse_to_tCsparse): new fast utility.
141            * src/Tsparse.h, init.c: ditto
142            * R/Auxiliaries.R (isTriT): new; faster than going via Csparse
143                 both isTriC() and isTriT() now return TRUE with "kind" or FALSE.

158    
159            * R/ngTMatrix.R: allow as(<numeric matrix>, "ngTMatrix") and hence
160            coercion to "nMatrix" and "pMatrix"
161    
162            * R/AllClass.R: "Schur" class;  "number" class union

177
