1    2008-01-24  Martin Maechler  <maechler@stat.math.ethz.ch>
2    
3            * R/Ops.R (.Arith.Csparse): new utility factored out of former
4              <dgC> o <dgC>, extended for triangular and also used in  <dtC> o <dtC>.
5    
6    2008-01-23  Martin Maechler  <maechler@stat.math.ethz.ch>
7    
8            * tests/factorizing.R (checkSchur): and more tests for checking Schur()
9    
10            * inst/test-tools.R (isOrthogonal): new function; also file restructured
11    
12    2008-01-22  Martin Maechler  <maechler@stat.math.ethz.ch>
13    
14            * R/ngTMatrix.R: allow as(<numeric matrix>, "ngTMatrix") and hence
15            coercion to "nMatrix" and "pMatrix"
16    
17            * R/AllClass.R: "Schur" class;  "number" class union
18            * man/number-class.Rd:
19            * man/Schur-class.Rd:
20    
21            * R/eigen.R (.dgeSchur): utility, and return "Schur" class
22            (.simpleSchur): Schur() method for diagonal matrices
23            (.triSchur):    Schur() method for triangular matrices
24            (Schur.sym):    Schur() for symmetric matrices {building on eigen()}.
25    
26    
27    2008-01-21  Martin Maechler  <maechler@stat.math.ethz.ch>

31    2008-01-15  Martin Maechler  <maechler@stat.math.ethz.ch>
32    
33            * R/CHMfactor.R (solve): method for b="numeric", but also b="ANY"
34                    in order to ensure 'system = *' is not lost;
35                    formals()$system instead of cut&paste.
36            * tests/factorizing.R: test solve(<CHM..>, <numeric>)
37    
38    2008-01-11  Martin Maechler  <maechler@stat.math.ethz.ch>

45    
46            * R/pMatrix.R: as(*, "matrix") now returns 0/1 *integer* matrix,
47                    and hence does as.vector(.).
48            * man/pMatrix-class.Rd: docs
49            * R/sparseMatrix.R: fix for printing "integer sparse"
50    
51            * tests/Class+Meth.R (tstMatrixClass): test M[FALSE], M[2] etc
52

54                    both "["   : (x, i,j, ..., drop)
55                    and  "[<-" : (x, i,j, ..., value)
56    
57            * R/denseMatrix.R: M[i] and M[i] <- v  (i vector) now work
58            * R/Tsparse.R (replTmat):    ditto
59            * R/diagMatrix.R (replDiag): ditto
60            * R/Csparse.R (replCmat):    ditto {was it worth the pain?}

75            * R/Matrix.R: "generic" cov2cor() method
76    
77            * R/nearPD.R: new 'only.values', 'keepDiag' arguments;
