7    
8            * DESCRIPTION (Version): 0.9975-10 to upload
9    
10            * tests/Class+Meth.R (tstMatrixClass): require coercions to
11            specific classes less unconditionally.
12    
13            * R/Auxiliaries.R: get rid of as_Tsparse() and as_Rsparse()
14    
15            * R/Tsparse.R (triu): etc, use as(*, "TsparseMatrix") instead of as_Tsparse()
16    
17            * R/Rsparse.R (.R.2.T): R-level workaround using compressed_to_TMatrix.
18            * R/Rsparse.R (.R.2.C): R-level workaround since C-level
19            R_to_CMatrix segfaults on one platform.
20            Eliminate most coercion method to *specific* classes, and replace
21            with virtual classes coercions.
22    
23    
24    2007-02-01  Martin Maechler <maechler@stat.math.ethz.ch>
25

108            * R/Auxiliaries.R (as_Csparse): and quite a few others:
109                    allow to pass class definition --> speedup
110            * R/sparseMatrix.R: apply the above
111    
112            * R/Csparse.R: coercion Csparse* to dense* now preserves shape properties.
113    
114            * src/Mutils.h (mMatrix_as_geMatrix): new, based on
115            * src/Mutils.c (dup_mMatrix_as_geMatrix): new; generalization of

119    
120            * R/denseMatrix.R (.dense2C): based on dense_to_Csparse: name it,
