1    2007-03-23  Martin Maechler  <maechler@stat.math.ethz.ch>
2    
3            * src/dtCMatrix.c (dtCMatrix_solve): use the new code from Kasper
4            Kristensen based cs_spsolve() instead of _lsolve & _usolve which
5            can be much faster.
6    
7            * tests/matprod.R: add regression tests for these (upper & lower).
8    
9    2007-03-19  Martin Maechler  <maechler@stat.math.ethz.ch>
10

14    
15    2007-03-17  Martin Maechler  <maechler@stat.math.ethz.ch>
16    
17            * R/Matrix.R (dim<-): new method for "reshape()" built on a

23    
24            * R/zzz.R (.onLoad, .onUnload): do *not* leave bind_activation(TRUE);
25            rather define cBind() and rBind();
26            and also cbind()/rbind {in Matrix, but exported}.
27

42    
43            * R/Ops.R (Arith): make sure Csparse o Csparse also works for e.g. ntCMatrix
44            * tests/simple.R: test the above and some of these coercions:
45    
46            * R/nsparseMatrix.R: coercing "Csparse" to "lsparseMatrix";
47                    be careful to avoid infinite recursion, using new coercions in

49            * R/lsparseMatrix.R: ditto
50    
51            * R/SparseM-conv.R: more conversion, notably for triplet matrices.

69            * R/Auxiliaries.R: get rid of as_Tsparse() and as_Rsparse()
70    
71            * R/Tsparse.R (triu): etc, use as(*, "TsparseMatrix") instead of as_Tsparse()
72    
73            * R/Rsparse.R (.R.2.T): R-level workaround using compressed_to_TMatrix.
74            * R/Rsparse.R (.R.2.C): R-level workaround since C-level
75            R_to_CMatrix segfaults on one platform.
76            Eliminate most coercion method to *specific* classes, and replace
77            with virtual classes coercions.
78    
79    
80    2007-02-01  Martin Maechler <maechler@stat.math.ethz.ch>
81

167    
168            * R/Csparse.R: coercion Csparse* to dense* now preserves shape properties.
169    
170            * src/Mutils.h (mMatrix_as_geMatrix): new, based on
171            * src/Mutils.c (dup_mMatrix_as_geMatrix): new; generalization of

175    
176            * R/denseMatrix.R (.dense2C): based on dense_to_Csparse: name it,
177            and use it for "sparse*" as well, since it's faster than the
178            as_Csparse(.) way.

189    
190            * R/Ops.R: "Compare" for (C|R)sparse: need pointer slot for all
191            FALSE answer
192    
193            * R/Csparse.R (replCmat): fix the "all non-zero" case with reordering
194            * tests/indexing.R: test it, and some of the above
195

205    
206            * R/zzz.R (tmp): for R >= 2.5.0, extend formals of our
207            base::as.matrix to (x, ...)
