This sort of aggregate function (over the rows) can be done in O(min(h+nnz, nnz*log(w))) time, but one would have to implement the algorithm for each of the above-mentioned 7 functions. By consolidating these into one templated function, it'll make it worth the effort to implement.</p> | This sort of aggregate function (over the rows) can be done in O(min(h+nnz, nnz*log(w))) time, but one would have to implement the algorithm for each of the above-mentioned 7 functions.

* | * There has to be a standard way to take an octave_value argument and call the proper template instantiation of a function based on its type. I started doing this with https://savannah.gnu.org/patch/?8417 , but diagonoal matrices still need to be added. The fact that the original implementer of find neglected to handle diagonal matrices should be evidence enough that the ad-hoc approach doesn't work. | ||
