Roman Donchenko	7ea1bf3cf0	Fixed several problems found by PVS-Studio. This fixes all problems from the article "Checking OpenCV with PVS-Studio" <http://www.viva64.com/en/b/0191/> that are not already fixed and are not in 3rdparty or the legacy module. The problems fixed are two instances of useless code and one instance of unspecified behavior (right-shifting a negative number).	11 years ago

Artanis	993522598b	Add implementations for Mat::zeros() and Mat::ones() In class Mat, "static MatExpr Mat::zeros(int ndims, const int* sz, int type)" and "static MatExpr Mat::ones(int ndims, const int* sz, int type)" are declared but never implemented. That means we can see their manuals from "http://docs.opencv.org/modules/core/doc/basic_structures.html" but we can't use them. Here I tried to finish their implementation. I have also changed MatOp_Initializer::assign to make it support multi-dimension Mat. Test cases are added in test_math.cpp as well.	12 years ago
