2    
3            * src/dsCMatrix.c (dsCMatrix_Csparse_solve): new
4            * R/dsCMatrix.R (solve): "fully-sparse" using the above.
5    
6            * R/AllClass.R: "pMatrix" now also inherits from "generalMatrix"
7    
8            * tests/Class+Meth.R (tstMatrixClass): now assure
9            the (important in method programming) property :
10    
11                    ###>>  Every "Matrix" is either
12                    ###>>  "general*", "symmetric*", "triangular*" or "diagonal*"
13    
14                    (where "*" stands for "Matrix")

20    
21            * R/sparseMatrix.R ([): improved indexing for sparse;
22                    trying to keep <symmetric>[ n, n] symmmetric
23    
24            * tests/indexing.R: indexing for logical sparse now ok
25

41            replacing both dgCMatrix_validate and lgCM*.
42    
43            * src/Csparse.c (Csparse_dense_prod, etc): do not lose dimnames;
44            fix dimnames setting in other places.
