2    
3            * R/Matrix.R (.M.sub.i.2col): fix for logical matrix indexing
4            * R/Tsparse.R (.TM.sub.i.2col, .TM.repl.i.2col): ditto;
5                    now, M[lower.tri(M)] and  M[lower.tri(M)] <- v  work better
6    
7            * src/Tsparse.c (Tsparse_to_tCsparse): new fast utility.
8            * src/Tsparse.h, init.c: ditto
9            * R/Auxiliaries.R (isTriT): new; faster than going via Csparse
10                 both isTriC() and isTriT() now return TRUE with "kind" or FALSE.
11            * R/sparseMatrix.R (isTriangular): hence simplified
12    
13    2008-01-24  Martin Maechler  <maechler@stat.math.ethz.ch>
14    
15            * R/Ops.R (.Arith.Csparse): new utility factored out of former
16              <dgC> o <dgC>, extended for triangular and also used in  <dtC> o <dtC>.
17    
18    2008-01-23  Martin Maechler  <maechler@stat.math.ethz.ch>
19    
20            * tests/factorizing.R (checkSchur): and more tests for checking Schur()
21    
22            * inst/test-tools.R (isOrthogonal): new function; also file restructured
23    
24    2008-01-22  Martin Maechler  <maechler@stat.math.ethz.ch>
25    
26            * R/ngTMatrix.R: allow as(<numeric matrix>, "ngTMatrix") and hence
27            coercion to "nMatrix" and "pMatrix"
28    
29            * R/AllClass.R: "Schur" class;  "number" class union
30            * man/number-class.Rd:
31            * man/Schur-class.Rd:
32    
33            * R/eigen.R (.dgeSchur): utility, and return "Schur" class
34            (.simpleSchur): Schur() method for diagonal matrices
35            (.triSchur):    Schur() method for triangular matrices
36            (Schur.sym):    Schur() for symmetric matrices {building on eigen()}.
37    
38    
39    2008-01-21  Martin Maechler  <maechler@stat.math.ethz.ch>
40    
41            * src/dgCMatrix.c (dgCMatrix_QR): set @Dim slot (as per doc)
42    
43  2008-01-15  Martin Maechler  <maechler@stat.math.ethz.ch>  2008-01-15  Martin Maechler  <maechler@stat.math.ethz.ch>
44    
45          * R/CHMfactor.R (solve): method for b="numeric", but also b="ANY"          * R/CHMfactor.R (solve): method for b="numeric", but also b="ANY"
