Description

The polynomial coefficients handed over to cv::solvePoly in cv::mat& coeffs should be interpreted as given in descending order of power (according to documentation on http://opencv.jp/opencv-2.2_org/cpp/core_operations_on_arrays.html#cv-solvepoly. )

But a quick test shows that they are interpreted in reverse order (which makes more sense, i agree, but should be fixed in the documentation).

To see this, just run enter the coefficients of a polynomial that is easily solvable manually (x^3^ + 1) in both ways into the function and look at the results.
