* CvMat.find_fundamental_mat_lmeds(<i>points1, points2[,options = {}]</i>) -> fundamental_matrix(cvmat) or nil
*
* Calculates fundamental matrix from corresponding points, use for LMedS algorism.
* <i>points1</i> and <i>points2</i> should be 2x7 or 3x7 single-channel, or 1x7 multi-channel matrix.
* <i>points1</i> and <i>points2</i> should be 2xN, Nx2, 3xN or Nx3 1-channel, or 1xN or Nx1 multi-channel matrix (N >= 8).
* <i>option</i> should be Hash include these keys.
* :with_status (true or false)
* If set true, return fundamental_matrix and status. [fundamental_matrix, status]
* Otherwise return fundamental matrix only(default).
* :maximum_distance
* The maximum distance from point to epipolar line in pixels, beyond which the point is considered an outlier
* and is not used for computing the final fundamental matrix. Usually it is set to 0.5 or 1.0.
* :desirable_level
* It denotes the desirable level of confidence that the matrix is correct.
