1308            * src/Mutils.h (mMatrix_as_geMatrix): new, based on
1309            * src/Mutils.c (dup_mMatrix_as_geMatrix): new; generalization of
1310            old dup_mMatrix_as_dgeMatrix), eliminating a long-standing "FIXME".
1311    
1312            * src/dense.c (dense_to_Csparse): use new mMatrix_as_geMatrix()
1313    
1314            * R/denseMatrix.R (.dense2C): based on dense_to_Csparse: name it,

1350            file; start using "Logic", hence
1351    
1352            * DESCRIPTION (Depends): R >= 2.4.1 (since we want "Logic")
1353            * NAMESPACE: import and export "Logic"

1412    
1413            * R/sparseMatrix.R (prSpMatrix): "." alignment much improved:
1414            align with proper position of "0", i.e., right for integers.
1415            argument 'align' by default is "fancy".

1441            to LL before converting to a sparse matrix. (The LDL form can be
