4529 6966 d 1 h bates /branches/Matrix-APIchange/ Creating a branch for the API changes from the 0.99875 series to the 0.999375 series  
3942 7207 d 21 h maechler /trunk/Matrix/ extend Csparse_Csparse_crossprod for tcrossprod (need test!); isSymmetric improved; misc.  
3940 7207 d 22 h bates /trunk/Matrix/ crossprod(<CsparseMatrix>,<CsparseMatrix>) added  
3876 7233 d 23 h maechler /trunk/Matrix/ Matrix(0, d,d) should also give sparse (not diagonal); general_to_symmetric; notably for lsC*; more coercions; first cut at Csparse_drop()  
3755 7258 d 17 h maechler /trunk/Matrix/ new nMatrix and subclasses; lsparse change to have x slot; many consequences  
3406 7286 d 18 h bates /trunk/Matrix/src/ Utilities Csparse_to_logical and Csparse_symmetric_to_general  
3404 7286 d 20 h bates /trunk/Matrix/ Use CHOLMOD code for general methods at CsparseMatrix, TsparseMatrix, denseMatrix or matrix level when possible  
3401 7288 d 21 h bates /trunk/Matrix/ Generalize conversions  
3134 7377 d 16 h bates /trunk/Matrix/ Generics lowerTriMatrix and upperTriMatrix and C function Csparse_band  
2304 7461 d 16 h bates /trunk/Matrix/ Used cholmod_vertcat and cholmod_horzcat for cbind2 and rbind2 in the dsparseMatrix virtual class  
2030 7545 d 22 h bates /trunk/Matrix/src/ Added crossprod method for Csparse and dense  
2022 7550 d 17 h bates /trunk/Matrix/ Matrix multiplication and coersion at higher level  
1836 7615 d 18 h bates /trunk/Matrix/ crossprod and tcrossprod for Tsparse  
1831 7616 d 15 h bates /trunk/Matrix/ More progress on incorporating CHOLMOD - still not passing CMD check  
1830 7616 d 22 h bates /trunk/Matrix/ Added CHOLMOD-based C functions. Still need methods defined in R and some error checking
