1    2007-03-27  Martin Maechler  <maechler@stat.math.ethz.ch>
2    
3            * R/kronecker.R: new file collecting kronecker() methods in one
4                    place.  Goal: become much faster!
5    
6    2007-03-23  Martin Maechler  <maechler@stat.math.ethz.ch>
7    
8            * src/dtCMatrix.c (dtCMatrix_solve): use the new code from Kasper
9            Kristensen based cs_spsolve() instead of _lsolve & _usolve which
10            can be much faster.
11    
12            * tests/matprod.R: add regression tests for these (upper & lower).
13    
14    2007-03-19  Martin Maechler  <maechler@stat.math.ethz.ch>

17    
18            * R/sparseMatrix.R (isDiagonal): check dim()!
19    
20    2007-03-17  Martin Maechler  <maechler@stat.math.ethz.ch>
21    
22            * R/Matrix.R (dim<-): new method for "reshape()" built on a

26    
27            * R/AllGeneric.R: remove all  if(!isGeneric(.))  clauses
28    
29            * R/zzz.R (.onLoad, .onUnload): do *not* leave bind_activation(TRUE);
30            rather define and export  cBind() and rBind() only.
31            --> useRs *must* change code that used to have cbind()/rbind() !!
32    
33            * R/bind.R: change tests from cbind() to cBind() and similarly to rBind()
34            * R/bind.Rout.save: ditto
35

51            * tests/simple.R: test the above and some of these coercions:
52    
53            * R/nsparseMatrix.R: coercing "Csparse" to "lsparseMatrix";
54                    be careful to avoid infinite recursion, using new coercions in

76            * R/Auxiliaries.R: get rid of as_Tsparse() and as_Rsparse()
77    
78            * R/Tsparse.R (triu): etc, use as(*, "TsparseMatrix") instead of as_Tsparse()
79    
80            * R/Rsparse.R (.R.2.T): R-level workaround using compressed_to_TMatrix.
81            * R/Rsparse.R (.R.2.C): R-level workaround since C-level
82            R_to_CMatrix segfaults on one platform.

84            with virtual classes coercions.
85    
86    
87    2007-02-01  Martin Maechler <maechler@stat.math.ethz.ch>

182    
183            * R/denseMatrix.R (.dense2C): based on dense_to_Csparse: name it,

198            FALSE answer
199    
200            * R/Csparse.R (replCmat): fix the "all non-zero" case with reordering
201            * tests/indexing.R: test it, and some of the above

212    
213            * R/zzz.R (tmp): for R >= 2.5.0, extend formals of our
214            base::as.matrix to (x, ...)
