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....
