将JAVA代码转换成MATLAB:import java.util.*; public class CenterTree { public static final int N = 5; // 中心树加上最近的四个点一共有5个点 public static void main(String[] args) { // 从控制台读取中心点坐标 Scanner scanner = new Scanner(System.in); System.out.print("请输入中心点坐标x:"); double cx = scanner.nextDouble(); System.out.print("请输入中心点坐标y:"); double cy = scanner.nextDouble(); Point center = new Point(cx, cy); // 从控制台读取最近的四个点的坐标 Point[] nearest = new Point[N-1]; for (int i = 0; i < nearest.length; i++) { System.out.printf("请输入最近的第%d个点坐标x:", i+1); double nx = scanner.nextDouble(); System.out.printf("请输入最近的第%d个点坐标y:", i+1); double ny = scanner.nextDouble(); nearest[i] = new Point(nx, ny); } // 计算每个点到中心点之间的夹角 List<Double> angles = new ArrayList<>(); for (Point p : nearest) { double dx = p.x - center.x; double dy = p.y - center.y; double radians = Math.atan2(dy, dx); double degrees = Math.toDegrees(radians); degrees = (degrees + 360) % 360; angles.add(degrees); } // 找到最小的四个夹角 List<Double> minAngles = new ArrayList<>(); for (int i = 0; i < nearest.length; i++) { // 找到当前点的相邻点 int nIndex = i == nearest.length - 1 ? 0 : i+1; // 计算相邻点到中心点的夹角 double dx = nearest[nIndex].x - center.x; double dy = nearest[nIndex].y - center.y; double radians = Math.atan2(dy, dx); double degrees = Math.toDegrees(radians); degrees = (degrees + 360) % 360; // 记录当前点和相邻点的夹角 double angle = Math.abs(angles.get(i) - degrees); angle = Math.min(angle, 360 - angle); minAngles.add(angle); } Collections.sort(minAngles); System.out.println(minAngles); // 计算最小的四个夹角的度数总和 double sum = 0; for (double angle : minAngles.subList(0, 4)) {

以下是将Java代码转换成MATLAB代码的结果:
```
N = 5;
cx = input('请输入中心点坐标x:');
cy = input('请输入中心点坐标y:');
center = [cx, cy];
nearest = zeros(N-1, 2);
for i = 1:N-1
nx = input(sprintf('请输入最近的第%d个点坐标x:', i));
ny = input(sprintf('请输入最近的第%d个点坐标y:', i));
nearest(i,:) = [nx, ny];
end
angles = zeros(1, N-1);
for i = 1:N-1
dx = nearest(i,1) - center(1);
dy = nearest(i,2) - center(2);
radians = atan2(dy, dx);
degrees = rad2deg(radians);
degrees = mod(degrees + 360, 360);
angles(i) = degrees;
end
minAngles = zeros(1, N-1);
for i = 1:N-1
nIndex = mod(i, N-1) + 1;
dx = nearest(nIndex,1) - center(1);
dy = nearest(nIndex,2) - center(2);
radians = atan2(dy, dx);
degrees = rad2deg(radians);
degrees = mod(degrees + 360, 360);
angle = abs(angles(i) - degrees);
angle = min(angle, 360 - angle);
minAngles(i) = angle;
end
sortedMinAngles = sort(minAngles);
disp(sortedMinAngles(1:4));
sum = 0;
for i = 1:4
sum = sum + sortedMinAngles(i);
end
```
请注意,由于Java和MATLAB的语法和数据结构有所不同,因此在转换过程中进行了适当的调整。同时,Java中的Scanner类被替换为MATLAB中的input函数,并且在MATLAB中需要手动创建大小为N-1的数组以保存最近的四个点的坐标。
