4994 6705 d 21 h maechler /trunk/Matrix/ my fast determinant(<dsC..>) versions  
4979 6716 d 11 h maechler /trunk/Matrix/ diagN2U() for preserving (unit-)triangularity in sparse (triang.)matrix multiplication  
4734 6921 d 21 h bates /trunk/Matrix/ Remove deprecated function writeHB and its methods; switch writeMM to use CHOLMOD code; repair readMM  
4573 6959 d 20 h maechler /trunk/Matrix/ Rsparse validation methods; finally make use of slot_dup() macro; fix R_to_C (symmetric)  
3942 7208 d 1 h maechler /trunk/Matrix/ extend Csparse_Csparse_crossprod for tcrossprod (need test!); isSymmetric improved; misc.  
3940 7208 d 3 h bates /trunk/Matrix/ crossprod(<CsparseMatrix>,<CsparseMatrix>) added  
3876 7234 d 3 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 21 h maechler /trunk/Matrix/ new nMatrix and subclasses; lsparse change to have x slot; many consequences  
3406 7286 d 22 h bates /trunk/Matrix/src/ Utilities Csparse_to_logical and Csparse_symmetric_to_general  
3404 7287 d 0 h bates /trunk/Matrix/ Use CHOLMOD code for general methods at CsparseMatrix, TsparseMatrix, denseMatrix or matrix level when possible  
3401 7289 d 2 h bates /trunk/Matrix/ Generalize conversions  
3134 7377 d 21 h bates /trunk/Matrix/ Generics lowerTriMatrix and upperTriMatrix and C function Csparse_band  
2304 7461 d 20 h bates /trunk/Matrix/ Used cholmod_vertcat and cholmod_horzcat for cbind2 and rbind2 in the dsparseMatrix virtual class  
2030 7546 d 3 h bates /trunk/Matrix/src/ Added crossprod method for Csparse and dense  
2022 7550 d 21 h bates /trunk/Matrix/ Matrix multiplication and coersion at higher level  
1836 7615 d 22 h bates /trunk/Matrix/ crossprod and tcrossprod for Tsparse  
1831 7616 d 19 h bates /trunk/Matrix/ More progress on incorporating CHOLMOD - still not passing CMD check  
1830 7617 d 3 h bates /trunk/Matrix/ Added CHOLMOD-based C functions. Still need methods defined in R and some error checking
