1    2006-12-10  Douglas Bates  <bates@stat.wisc.edu>
2    
3            * src/CHMfactor.c (CHMfactor_to_sparse): change LDL factorization
4            to LL before converting to a sparse matrix. (The LDL form can be
5            converted to a sparse matrix but it is implicitly a unit
6            triangular matrix and a diagonal matrix overwritten on the diagonal.)

8    2006-12-09  Douglas Bates  <bates@stat.wisc.edu>
9    
10            * src/chm_common.c (chm_factor_to_SEXP): allocate and fill the Dim slot.

23            * src/dgeMatrix.c (dgeMatrix_solve): Check error code from dgetri.
24            * tests/dg_Matrix.R: Add Barry Rowlingson's test of a matrix that
25            is exactly singular.

33            * R/Csparse.R (replCmat): symmetric indexing of symmetric matrix
34            now returns symmetric.

37    
38            * R/Matrix.R (.M.sub.i.2col):  new, for  M[ cbind(i,j) ] indexing.

46            running src/CSparse_install.sh
47    
48            * R/denseMatrix.R: "[": keep symmetric on symmetric indexing.
