x=0:1:15; a=x-5; b=2+sin(x); y=a/b; plot(x,y,'r')为什么生成不出图像

因为在 b=2 sin(x) 的表达式中,sin(x) 参数应使用弧度制,而不是角度制。因此,可以使用 deg2rad(x) 函数将角度转换为弧度,然后再计算 b 的值。修改代码如下:
```
x = 0:1:15;
a = x - 5;
b = 2*sin(deg2rad(x));
y = a./b;
plot(x,y,'r');
```
这样就可以生成图像了。

x=0:1:15; a=x-5; b=2+sin(x); y=a/b; plot(x,y,'r')
As an AI language model, I cannot generate a plot. However, I can explain the code:
- The first line creates a vector `x` with values ranging from 0 to 15 in steps of 1.
- The second line creates a new vector `a` which is equal to `x-5`.
- The third line creates a new vector `b` which is equal to `2 sin(x)`, where `sin` is the sine function in radians.
- The fourth line creates a new vector `y` which is equal to `a/b`.
- The last line plots the vector `y` against `x` using a red color.
用MATLAB显示y=abs((x-5)/(2+sin(x)))的图像
可以使用以下代码来显示y=abs((x-5)/(2*sin(x)))的图像:
```matlab
x = linspace(0, 10, 1000); % 生成x轴坐标
y = abs((x-5)./(2*sin(x))); % 计算y轴坐标
plot(x, y) % 绘制图像
grid on % 显示网格线
xlabel('x') % 设置x轴标签
ylabel('y') % 设置y轴标签
title('y=abs((x-5)/(2*sin(x)))') % 设置标题
```
运行以上代码,即可得到如下图像:
