% Finds the indices of the cell that holds the minimum cost%% Input%   costs : The matrix that contains the estimation costs for a macroblock%% Output%   dx : the motion vector component in columns%   dy : the motion vector component in rows%% Written by Aroh Barjatyafunction [dx, dy, min] = minCost(costs)[row, col] = size(costs);% we check whether the current% value of costs is less then the already present value in min. If its% inded smaller then we swap the min value with the current one and note% the indices.min = 65537;for i = 1:row    for j = 1:col        if (costs(i,j) < min)            min = costs(i,j);            dx = j; dy = i;        end    endend
