3543 7268 d 0 h maechler /branches/Matrix-for-R-2.3.x/ branching an "old-R" compatible version of Matrix  
3519 7272 d 0 h bates /trunk/Matrix/ Generalize %*% methods for sparse matrices  
3502 7275 d 13 h bates /trunk/Matrix/ Move methods to the CsparseMatrix class  
3401 7288 d 23 h bates /trunk/Matrix/ Generalize conversions  
3379 7293 d 22 h bates /trunk/Matrix/ Set stype in C function Csparse_crossprod and avoid R-level conversions  
3374 7294 d 8 h maechler /trunk/Matrix/ tril() etc also for T* and Rsparse  
3340 7309 d 23 h maechler /trunk/Matrix/ many method cleanups; notably some "dgC" -> "Csparse" generaliztations  
3338 7311 d 10 h maechler /trunk/Matrix/ miscellaneous mostly related to sparse indexing  
3226 7352 d 19 h maechler /trunk/Matrix/ coercion to and multiplication of diagonal and sparse matrices  
3218 7354 d 7 h maechler /trunk/Matrix/ implemented all 4 of {rowSums(), ... colMeans()}  
3172 7370 d 9 h maechler /trunk/Matrix/ useDynlib(*, .registration=TRUE)  
3148 7375 d 10 h maechler /trunk/Matrix/ cosmetic, comments  
3139 7376 d 21 h bates /trunk/Matrix/ single argument [t]crossprod now returns a symmetric matrix  
3133 7377 d 20 h maechler /trunk/Matrix/ Tsparse indexing fix  
3034 7423 d 21 h maechler /trunk/Matrix/ coercions from dgC to triangular (dtC) and symmetric (dsC), etc  
2357 7441 d 3 h maechler /trunk/Matrix/ sparse: "[<-" and better arithmetic; other tweaks  
2304 7461 d 18 h bates /trunk/Matrix/ Used cholmod_vertcat and cholmod_horzcat for cbind2 and rbind2 in the dsparseMatrix virtual class  
2059 7534 d 20 h maechler /trunk/Matrix/ make tcrossprod() use 2 arguments (x, y=NULL)  
2022 7550 d 18 h bates /trunk/Matrix/ Matrix multiplication and coersion at higher level  
1871 7603 d 21 h maechler /trunk/Matrix/R/ add "self-documenting" argument names  
1836 7615 d 19 h bates /trunk/Matrix/ crossprod and tcrossprod for Tsparse  
1833 7615 d 22 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  
1831 7616 d 17 h bates /trunk/Matrix/ More progress on incorporating CHOLMOD - still not passing CMD check  
1783 7633 d 3 h maechler /trunk/Matrix/ move some methods from lgT to lsparse  
1777 7634 d 23 h maechler /trunk/Matrix/ new classes "index", "symmetricM*" and "triangularM*"; indexing for logical and character indices; new tests; more to do  
1766 7638 d 19 h maechler /trunk/Matrix/ indexing (mainly denseMatrix) - using "vector" indices  
1745 7647 d 0 h maechler /trunk/Matrix/ new "gTMatrix" virtual class
