WebOct 30, 2013 · About the SolveLinearEquations Function A set of Linear equations are represented by the matrix equation: aMatrix xVector = bVector The aMatrix and bVector are given, and the xVector is the solution. The first example set of equations given above can be rewritten as: 3 X + 4 Y + 5 Z = 0 1 X - 10 Y + 1 Z = 0 1 X + 0 Y + 1 Z = 42.5 WebJul 10, 2014 · 2 Answers. Sorted by: 2. You're using Point (int _x, int _y) but supplying (row,col) according to your for loops. It'll crash unless you have a square frame, but with more columns than rows, your going to read a lot further out of the frame's data buffer and probably crash sooner. This is because cv::Mat stores data in row-major order (one row ...
