可以用matlab提供的坐标轴设置函数axis进行设置(对当前坐标轴进行设置),具体用法如下:1、plot(x, y); // 画图后用axis函数设置坐标轴的范围。2、axis([xmin xmax ymin ymax]); % 设置坐标轴在指定的区间。3、xmin、xmax 表示设置横坐标的最小最大值。4、ymin、ymax 表示设置纵坐标的最小...
一种方法是在绘制图形之前,先保存你的数据点到一个变量中,然后你可以通过访问这个变量来查看具体的XY坐标值。例如,如果你有一组X值和一组Y值,你可以这样做:```matlab 假设X和Y是你的数据点 X = 1:10; % 从1到10的整数 Y = X.^2; % Y是X的平方 绘制图形 plot(X, Y);现在,如果...

plot(x, y);直接在命令窗口查看x和y的值 disp('X坐标值为:');disp(x);disp('Y坐标值为:');disp(y);```这段代码会在MATLAB的命令窗口中显示x和y的所有坐标值,而不是通过图形或表格的形式。这种方法适用于你已知或需要查看绘图所用到的全部数据点的情况。如果你需要查看图形上特定点的...
