If they have c interface, you can just call like that you had done in openssl. That said, I guess passing data in and out of GPU memory is an expensive operation. Пн, 21 сен 2015, jprogramming написал(а): > They have a c interface too. Its just harder to find the c versions of the > api sometime

Arrayfile looks like c++ library, it is difficult to be called from J as a shared object. Пн, 21 сен 2015, jprogramming написал(а): > I was worried about the parentheses being part of the 'operator()' name, but > I found this page which has accessible versions: > > http://www.arrayfire.com/docs

I was worried about the parentheses being part of the 'operator()' name, but I found this page which has accessible versions: http://www.arrayfire.com/docs/group__index__func__index.htm It also looks like their span "keyword" could be a null parameter. - Original Message - From: Raul M

Well, I guess we only really need 1 or 2 dimensions from AF, so maybe that's no big deal. And we get to decide what we call a row and what we call a column. Meanwhile, http://www.jsoftware.com/help/user/lib_dll.htm http://www.jsoftware.com/papers/jfe.htm require'dll' cdcb 15!:13 The dll c

I did suggest a rankselect and rankamend function to the lead developer. AF has either a max 3 or 4 dimensions on its arrays. Its column (wrong) major. http://www.arrayfire.com/docs/indexing.htm to get rows 0 and 1 from a 2d array, you would call with 0 1;(seq 0 _1). For columns 1 and 2, c

I don't think anyone has been working on this. Note also that J's arrays are built on a C infrastructure where a pair of one dimensional arrays (shape and data) represent an arbitrary dimensioned J array. That said... how hard do you think it would be to implement the rank conjunction? (Rank migh
