364    
365            * R/Auxiliaries.R (as_Csparse): and quite a few others:
366                    allow to pass class definition --> speedup
367            * R/sparseMatrix.R: apply the above
368    
369            * R/Csparse.R: coercion Csparse* to dense* now preserves shape properties.
370    
371            * src/Mutils.h (mMatrix_as_geMatrix): new, based on
372            * src/Mutils.c (dup_mMatrix_as_geMatrix): new; generalization of

377            * R/denseMatrix.R (.dense2C): based on dense_to_Csparse: name it,

379            as_Csparse(.) way.
