代码说明：

  输入椭圆中心和长短轴径; 2. 计算得到中心在原点的椭圆上的第一个点=; 3. 根据公式(1.1.3-2)计算区域1中决策参数的初值为; 4. 在区域1中每个位置处，从开始，反复按照公式(1.1.3-3)更新决策参数，若决策参数小于0则不变，反之加1，一直循环到为止，记第一个满足此条件的点为(); 5. 在区域2的每个位置处，从开始，反复按照公式(1.1.3-6)更新决策参数，若决策参数小于0则不变，反之加1，一直循环到()为止;(Input ellipse center and long and short axis diameter; 2. The first point of the center on the ellipse at the origin is calculated. 3. According to formula (1.1.3-2), the initial value of decision-making parameters in region 1 is calculated. 4. At each location in region 1, the decision-making parameters are updated repeatedly according to formula (1.1.3-3). If the decision-making parameters are less than 0, they will remain unchanged. If the decision-making parameters are less than 0, then add 1 and cycle until the first point satisfying this condition is (); 5. At each location of region 2, the decision parameters are updated repeatedly according to the formula (1.1.3-6). If the decision parameters are less than 0, they will remain unchanged. If the decision parameters are less than 0, then add 1 and cycle until ().)
