printf System Toolbox 或者版本不兼容导致的。
可以通过打开Matlab的“Add-Ons”菜单,找到("Please input course (input 'all' to query all evaluations): ");
scanf("%s", course);
printf("Please input studentControl System Toolbox并安装,或者更新Control System Toolbox到最新版本来解决此问题。

scanf("%s", student_id);
printf("Please input teacher id (input 'all' to query all evaluations): ");
scanf("%s", teacher_id);

```
% 定义过程数据

(strcmp(student_id, "all") == 0 || strcmp(evaluations[i].student_id, student_id) == 0) &&
(strcmp(teacher_id, "all") == 0 || strcmp(evaluations[i].2];

LCL = mu - 3*sigma/sqrt(length(data));

evaluations[i].course, evaluations[i].student_id, evaluations[i].% 绘制T方控制图
figure;
plot(data, 'bo-');
hold on;
plot([1 length(data)], [Uteacher_id,
evaluations[i].score, evaluations[i].comment);
}
}
}
// 学生评价
void evaluateCL UCL], 'r--');
plot([1 length(data)], [LCL LCL], 'r--');

ylabel('样本值');

```
这段代码中,我们手动绘制了[100];
printf("Please input course: ");
scanf("%s", course);
printf("Please input teacher id: ");
数据点和控制限线。其中,'bo-'表示使用蓝色圆点连接数据点,'r--'表示使用 scanf("%s", teacher_id);
printf("Please input your student id: ");
scanf("%s", student_id);
printf("红色虚线绘制控制限。最后,我们添加了x轴和y轴的标签,以及图像Please input score (0-100): ");
scanf("%d", &score);
printf("Please input comment (less than 100 characters的标题。
