1 第一，启动MATLAB，新建脚本（Ctrl+N），输入如下代码：close all;clear all;clcx=0:pi/50:2*pi;y=sin(x);hline1=plot(x,y,'k','linewidth',3);hline2=line(x+0.05,y,'linewidth',4,'color',[.8,.8,.8]);set(gca,'children',[...
Hi, I am plotting the experimental data and fitted line using matlab plot. The legend command shows the markers (data points) and line (fit) as a separate legend entry. However, I am interested to obtain the marker and line in a single legend entry so that the total number of legend ...
2.ezplot和fplotezplot是easy plot的简称，意思就是简化画图，只需给出函数体而无需变量范围，例如想画个圆，用ezplot就很方便：syms x yezplot('x^2+y^2=1',[-1.5 1.5],[-1 1])fplot的意思是function plot，就是画某一函数的曲线。顾名思义,若要画一条函数的曲线，只要给出函数名和...

matlab中num2str的应用 precision为3表示保留最多3位有效数字, 例如0.5345转换后为0.534,1.2345转换后为1.23。即从左边第一个不为0的数开始保留3个数值。str=num2str(A...】。 在求导数,积分,方程的过程中,难免会遇到一些参数要随着情况有点变化,这时,你就需要能够动态的表示出你的表达式,Num2str函数是一个相当有...
lineSpec包含设置线条样式(line-style),标记符号(marker)和颜色(color) , 表示对plot绘制图形的样式、标记符合和颜色进行调整 。 三个属性没有顺序,如果缺少一个,则表示没有 matlab文档中提供了所有的样式颜色符号表,help plot 可以查看参考页的input Arguments(输入参数)中的LineSpec,可以查看line-style、marker、colo...
To create a horizontal line, we can use the Matlab built-in functionyline(), which plots a horizontal line with a constant vertical value. For example, let’s plot a horizontal line on a specific vertical position on a graph. See the code below. ...
MATLAB®creates plots using a default set of line styles, colors, and markers. These defaults provide a clean and consistent look across the different plots you create. If you want, you can customize these aspects of your plot. Many plotting functions have an input argument calledlinespecfor ...
EN本文为matlab自学笔记的一部分，之所以学习matlab是因为其真的是人工智能无论是神经网络还是智能计算中...
line(x,y) plots a line in the current axes using the data in vectors x and y. If either x or y, or both are matrices, then line draws multiple lines. Unlike the plot function, line adds the line to the current axes without deleting other graphics objects or resetting axes properties...
