AFAICS, is it > because the return values are passed by pointer to it? I meant there is no mat.cwise().sincos() function yet, which I guess should be an "in place" function taking two matrices. its implementation is not completely trivial (not difficult though) because we cannot reuse existing Eigen's mechanism. Said that I can still add the low level ei_psincos() function, but it won't be used until someone write the high level function. hm... I'm thinking that perhaps the trick we used for swap could work here too.... > -- > Rohit Garg > > http://rpg-314.blogspot.com/ > > Senior Undergraduate > Department of Physics > Indian Institute of Technology > Bombay > > >
