3            * R/dgeMatrix.R: need solve(<dge>, <sparse>) against infinite
4            recursion in new test in
5            * tests/matprod.R: testing the above and another solve() case, below
6    
7            * R/sparseMatrix.R (lm.fit.sparse): slightly more efficient for
8            e.g. triangular 'x'.
9    
10            * src/dgCMatrix.c (dgCMatrix_qrsol): use AS_CSP() hence allowing dtC*
11            * src/dgCMatrix.c (dgCMatrix_cholsol): use AS_CHM_SP() to work
12            correctly with unit-triangular x
13    
14            * src/dsCMatrix.c (dsCMatrix_Csparse_solve): use AS_CHM_SP()
15            instead of not checking diagU.

17            * R/diagMatrix.R, R/Auxiliaries.R: tweaks to allow later
18            experiments where diagonalMatrix would extend sparse*.

27            * src/chm_common.c (as_cholmod_sparse): Do not use LENGTH(islot)

30            * tests/validObj.R: more testing of over-allocated (i,x) slots
31    
32    2008-07-23  Martin Maechler  <maechler@stat.math.ethz.ch>
