function [fundamentalMatrix]=estimateFundamentalMatrix(matchedPoints1,matchedPoints2,varargin)
// It returns the 3-by-3 fundamental matrix corresponding to the input points
//
// Calling Sequence
//   fundamentalMat=estimateFundamentalMatrix(matchedPoints1,matchedPoints2);
//	 fundamentalMat=estimateFundamentalMatrix(matchedPoints1,matchedPoints2,'method','RANSAC','param1',2,'param2',0.99);
//
// Parameters
// matchedPoints1:  M-by-2 array of first image points. These points can be SURFPoints, MSERRegions, cornerPoints. 
// matchedPoints2:  M-by-2 array of the second image points of the same size and format as matchedPoints1.
// method: method for computing fundamental matrix. Possible methods are 7POINT,8POINT,RANSAC,LMEDS and RANSAC is the default one. 
// param1: It indiacates maximum distance from a point to an epipolar line in pixels
// param2: It specifies a desirable level of confidence
//
// Description
// estimateFundamentalMatrix function calculates a fundamental matrix from the corresponding points in two images.
//
// Examples
// I=imread("lena_left.jpeg");
// cornerPoints1=detectMinEigenFeatures(I);
// I2=imread("lena_right.jpeg");
// cornerPoints2=detectMinEigenFeatures(I2);
// fundamentalMat=(cornerPoints1.Location,cornerPoints2.Location);
