2013-01-05 17:58:51 -0600	commented answer	What data types can I use for a complex OutputArray? Thanks for the link! Although I don't really think that answers my question (I may have missed it). I know I can use a Mat object as an OutputArray—I'm wondering if I can use a std::vector<std::complex<double>>. Also, I'm using this to analyze simulated neutrino detector data.

2013-01-04 07:52:23 -0600	asked a question	Basic matrix operations producing null pointer members Please bear with me, I'm totally new to OpenCV. array1 and array2 primitive arrays of doubles, of the same length. `cv::Mat_<double> A (lengthOfArray1, 1, array1); cv::Mat_<double> B (lengthOfArray1, 1, array2); cv::Mat_<double> C = A - B;` The problem is that what I get for C is an array with the right dimensions but a null pointer data, refcount, datastart, dataend, datalimit, and allocator. I must be doing something silly.
