22    
23            * DESCRIPTION (LicenseDetails): new; such that 'License:' becomes "canonical"
24

44    2008-02-20  Martin Maechler  <maechler@stat.math.ethz.ch>
45    
46            * R/Matrix.R (Matrix): no longer use coercions to specific classes

905            * R/sparseMatrix.R: apply the above
906    
907            * R/Csparse.R: coercion Csparse* to dense* now preserves shape properties.
908    
909            * src/Mutils.h (mMatrix_as_geMatrix): new, based on
910            * src/Mutils.c (dup_mMatrix_as_geMatrix): new; generalization of

949    
950            * R/Ops.R ("Arith" etc): move almost all "Ops" methods to new R
951            file; start using "Logic", hence

1099                    ###>>  "general*", "symmetric*", "triangular*" or "diagonal*"

1185    
1186            * src/Csparse.c (Csparse_validate): fixed (and more efficient in
