1    2007-04-12  Martin Maechler  <maechler@stat.math.ethz.ch>
2    
3            * R/dgTMatrix.R (mat2dgT): care about NAs
4    
5    2007-04-11  Martin Maechler  <maechler@stat.math.ethz.ch>
6    
7            * R/kronecker.R: triangularity preserving methods
8    
9    2007-03-27  Martin Maechler  <maechler@stat.math.ethz.ch>
10    
11            * R/kronecker.R: new file collecting kronecker() methods in one
12                    place.  Goal: become much faster!
13    
14    2007-03-23  Martin Maechler  <maechler@stat.math.ethz.ch>
15    
16            * src/dtCMatrix.c (dtCMatrix_solve): use the new code from Kasper
17            Kristensen based cs_spsolve() instead of _lsolve & _usolve which
18            can be much faster.
19    
20            * tests/matprod.R: add regression tests for these (upper & lower).
21    
22    2007-03-19  Martin Maechler  <maechler@stat.math.ethz.ch>
23    
24            * R/Matrix.R (diff): method for our Matrices.

38            rather define and export  cBind() and rBind() only.
39            --> useRs *must* change code that used to have cbind()/rbind() !!
40    
41            * R/bind.R: change tests from cbind() to cBind() and similarly to rBind()
42            * R/bind.Rout.save: ditto
43

58            * R/Ops.R (Arith): make sure Csparse o Csparse also works for e.g. ntCMatrix
59            * tests/simple.R: test the above and some of these coercions:
60    
61            * R/nsparseMatrix.R: coercing "Csparse" to "lsparseMatrix";
62                    be careful to avoid infinite recursion, using new coercions in
63            * R/ngCMatrix.R and nsC... and ntC...
64            * R/lsparseMatrix.R: ditto
65    
66            * R/SparseM-conv.R: more conversion, notably for triplet matrices.

83    
84            * R/Auxiliaries.R: get rid of as_Tsparse() and as_Rsparse()
85    
86            * R/Tsparse.R (triu): etc, use as(*, "TsparseMatrix") instead of as_Tsparse()
87    
88            * R/Rsparse.R (.R.2.T): R-level workaround using compressed_to_TMatrix.
89            * R/Rsparse.R (.R.2.C): R-level workaround since C-level
90            R_to_CMatrix segfaults on one platform.
91            Eliminate most coercion method to *specific* classes, and replace
92            with virtual classes coercions.
93    
94    
95    2007-02-01  Martin Maechler <maechler@stat.math.ethz.ch>
96

190    
191            * R/denseMatrix.R (.dense2C): based on dense_to_Csparse: name it,

206            FALSE answer
207    
208            * R/Csparse.R (replCmat): fix the "all non-zero" case with reordering
209            * tests/indexing.R: test it, and some of the above

220    
221            * R/zzz.R (tmp): for R >= 2.5.0, extend formals of our
222            base::as.matrix to (x, ...)
