在MATLAB中平滑2D图 [英] smoothing 2D plot in MATLAB

问题描述

我在MATLAB中有一些简单的图，

I have some simple plot like this in MATLAB:

x = [0:5:25];
y = [1 4 7 9 8 3];
plot(x,y)

我的问题是如何使它平滑?在文档中找不到我想要做的任何事情.

My question is how can I smooth it? Haven't found any way of doing what I want in documentation.

推荐答案

也许您可以按如下方式使用spline

Maybe you could make use of spline as follows

x1 = 0:.1:25;
y1 = spline(x,y,x1);
plot(x,y,x1,y1);
