matlab scatter3与plot3

之间有什么区别?
scatter3和plot3都可以在三维坐标系中绘制点,但两者有不同之处。scatter3可以按照指定的颜色和大小显示每个点,非常适合显示密度图;而plot3则是将所有点用一条线连接起来,适合显示数据的连续性。因此,scatter3更适合用于离散的非连续数据,而plot3则更适合用于连续的数据。

matlab scatter
scatter函数用于在二维平面中绘制散点图。语法格式如下:
scatter(x,y)
scatter(x,y,s)
scatter(x,y,s,c)
scatter(x,y,s,c,marker)
scatter(ax,...)
其中,x和y是数据点的横纵坐标,s表示数据点的大小,c表示数据点的颜色,marker表示数据点的形状。ax表示要在其中绘图的axes对象。
例如,下面的代码绘制了一个随机数据的散点图:
x = rand(100,1);
y = rand(100,1);
scatter(x,y)
如果要给散点图添加标题和坐标轴标签,可以使用以下代码:
x = rand(100,1);
y = rand(100,1);
scatter(x,y)
title('My Scatter Plot')
xlabel('X-axis')
ylabel('Y-axis')

matlab plot
As an AI language model, I don't have GUI to show you the MATLAB plot. However, I can guide you with the code to create a MATLAB plot.
Here is a basic example of how to create a simple 2D line plot in MATLAB:
```
x = linspace(0, 10, 100); % Create a vector of 100 points from 0 to 10
y = sin(x); % Calculate the sine of each point in x
plot(x, y); % Plot x vs. y
title('Sine Wave'); % Add a title to the plot
xlabel('X'); % Label the x-axis
ylabel('Y'); % Label the y-axis
```
This code will create a plot of a sine wave, with the x-axis labeled "X", the y-axis labeled "Y", and a title of "Sine Wave". You can modify the code to create different types of plots, such as scatter plots, bar graphs, or 3D plots.
