4483 6977 d 20 h maechler /trunk/Matrix/ colSums, ... rowMeans for all Matrices; notably sparse ones via [diln]gCMatrix_colSums C code  
4032 7162 d 23 h maechler /trunk/Matrix/ any(), all() and "Compare"(<sparse>) - for release of 0.9975-7  
3943 7207 d 1 h maechler /trunk/Matrix/ tcrossprod(<Csp>, <Csp>); dimnames for [t]crossprod; validity now ensures correct length(Dimnames[[j]])  
3942 7207 d 18 h maechler /trunk/Matrix/ extend Csparse_Csparse_crossprod for tcrossprod (need test!); isSymmetric improved; misc.  
3940 7207 d 20 h bates /trunk/Matrix/ crossprod(<CsparseMatrix>,<CsparseMatrix>) added  
3755 7258 d 14 h maechler /trunk/Matrix/ new nMatrix and subclasses; lsparse change to have x slot; many consequences  
3534 7268 d 21 h maechler /trunk/Matrix/ miscellaneous tweaks; moved some method definitions higher up  
3520 7271 d 14 h bates /trunk/Matrix/ Promotion of %*% and solve to RHS of ddenseMatrix  
3517 7271 d 22 h bates /trunk/Matrix/ Promote %*% methods to ddenseMatrix class  
3413 7285 d 18 h maechler /trunk/Matrix/man/ update methods list  
3405 7286 d 17 h bates /trunk/Matrix/ Use CHOLMOD code for general methods at CsparseMatrix, TsparseMatrix, denseMatrix or matrix level when possible  
3403 7288 d 18 h bates /trunk/Matrix/ Generalize conversions  
3340 7309 d 18 h maechler /trunk/Matrix/ many method cleanups; notably some "dgC" -> "Csparse" generaliztations  
3338 7311 d 5 h maechler /trunk/Matrix/ miscellaneous mostly related to sparse indexing  
3218 7354 d 3 h maechler /trunk/Matrix/ implemented all 4 of {rowSums(), ... colMeans()}  
3175 7368 d 21 h maechler /trunk/Matrix/man/ start massive use of \linkS4class{.}  
2059 7534 d 15 h maechler /trunk/Matrix/ make tcrossprod() use 2 arguments (x, y=NULL)  
2022 7550 d 14 h bates /trunk/Matrix/ Matrix multiplication and coersion at higher level  
1833 7615 d 17 h maechler /trunk/Matrix/ too many changes: rbind2 for dM*, cbind2(), "Math", "Arith" for sparse ones; more "s/gTMatrix/TsparseMatrix/" fixes; quite a few more tests, incl some for *all* classes
