356    
357            * R/kronecker.R: new file collecting kronecker() methods in one
358                    place.  Goal: become much faster!

361    
362            * src/dtCMatrix.c (dtCMatrix_solve): use the new code from Kasper
363            Kristensen based cs_spsolve() instead of _lsolve & _usolve which
364            can be much faster.

385            --> useRs *must* change code that used to have cbind()/rbind() !!
386    
387            * R/bind.R: change tests from cbind() to cBind() and similarly to rBind()
388            * R/bind.Rout.save: ditto

406    
407            * R/nsparseMatrix.R: coercing "Csparse" to "lsparseMatrix";
408                    be careful to avoid infinite recursion, using new coercions in

433    
434            * R/Rsparse.R (.R.2.T): R-level workaround using compressed_to_TMatrix.
435            * R/Rsparse.R (.R.2.C): R-level workaround since C-level
436            R_to_CMatrix segfaults on one platform.

447            all as(<from>, <to>)
448
