5    2006-11-06  Martin Maechler  <maechler@stat.math.ethz.ch>
6    
7            * R/Csparse.R (replCmat): symmetric indexing of symmetric matrix
8            now returns symmetric.
9

11    
12            * R/Matrix.R (.M.sub.i.2col):  new, for  M[ cbind(i,j) ] indexing.
13            * R/Matrix.R (.M.repl.i.2col): new, for  M[ cbind(i,j) ] <- value

18    
19            * src/cs.[ch]: updated to CSparse Version 2.0.3 by simply
20            running src/CSparse_install.sh
21    
22            * R/denseMatrix.R: "[": keep symmetric on symmetric indexing.

30    
31            * tests/Class+Meth.R (tstMatrixClass): now assure
32            the (important in method programming) property :
33    
34                    ###>>  Every "Matrix" is either
35                    ###>>  "general*", "symmetric*", "triangular*" or "diagonal*"

42            * tests/validObj.R: checks for "comparison"
43    
44            * R/sparseMatrix.R ([): improved indexing for sparse;
45                    trying to keep <symmetric>[ n, n] symmmetric
46    
47            * tests/indexing.R: indexing for logical sparse now ok
48

60            * tests/simple.R: validObject() checking the above.
61    
62            * src/dgCMatrix.c (xCMatrix_validate): new, small and simple,
63            replacing both dgCMatrix_validate and lgCM*.
64    
65            * src/Csparse.c (Csparse_dense_prod, etc): do not lose dimnames;
66            fix dimnames setting in other places.

121    
122            * src/Csparse.c (Csparse_validate): fixed (and more efficient in

131            coercion; deprecating direct lower level coercions.
132    
133            * R/*.R (seq): use seq_len() and seq_along() where possible.
134    
135    
136    2006-10-23  Martin Maechler  <maechler@stat.math.ethz.ch>
