根据你提供的代码,我看到了问题所在。在while循环中,判断结束的条件应该是`new_cover >= 0.95`,而不是`new_cover < 0.95`。此外,在记录覆盖率变化时,需要在循环内部更新`cover`的值。
下面是修改后的代码段:
```matlab
clc,clear
% 生成初始点
x=rand*100;
y=rand*100;
jiedian = [x,y];
% 初始化参数
p = 1e6;
n = 0;
% 计算初始覆盖率
area = mengtekaluo(jiedian);
cover = area / 1e5;
new_cover = [];
new_cover = [new_cover;cover];
% 记录覆盖率的变化
cover_history = [];
cover_history = [cover_history;cover];
% 随机生成点,进行循环判断覆盖率是否达到目标值
while new_cover >= 0.95
flag1 = 1;
x_new = rand * 100;
y_new = rand * 100;
jiedian = [jiedian; x_new, y_new];
for i = 1:p % 对于要投放的总共p个点
n = 0;
flag = 0;
px = rand*100; % 随机生成该点的横坐标
py = rand*100; % 随机生成该点的纵坐标
[a,~] = size(jiedian);
for j = 1 : a
if (px-jiedian(j,1))^2 + (py-jiedian(j,2))^2 < 100 % 检查点与已有节点的距离是否小于10
flag = flag + 1;
end
end
if flag == a
n = n + 1;
end
end
area = (n/p)*10000;
new_cover = area / 1e5;
if (new_cover - cover) / cover < 0.1
flag1 = 0; % 用flag判断覆盖率变化
new_cover = cover;
end
% 更新覆盖率和记录覆盖率的变化
cover = new_cover;
cover_history = [cover_history; cover];
end
% 绘制覆盖率变化曲线
hold on;
figure;
plot(1:length(cover_history), cover_history);
xlabel('生成节点数量');
ylabel('区域覆盖率');
title('区域覆盖率变化');
```
这样修改后,代码应该能够正确计算和记录区域的覆盖率变化了。
