可以看到该图与stem生成的图的区别就在于一个是连线图,一个是点线图。 plot(Y)创建Y中数据对每个值索引的二维线图。 如果Y是向量,x轴的刻度范围是从 1 至length(Y)。 如果Y是矩阵,则plot函数绘制Y中各列对其行号的图。x轴的刻度范围是从 1 到Y的行数。 如果Y是复数,则plot函数绘制Y的虚部对Y的实部的...
第三种使用方法,意思是把n个图像做出在一个窗口中,同时也少敲了几个plot,当然,如果你想把代码分开写也可以,只需要加上hold on命令就行了,关于它后文会有介绍。 (2)fplot * fplot(f,lims,参数) * fplot(funx,funy,tlims,参数) 在第一种方法中,f代表一个函数,通常采用函数句柄的形式。lims为x轴的取值...
stem() 函数用来画一张整图,画出来是离散函数。stem(x) 如果x是一个数组,图像就显示为在x轴上等距离排列的离散数据以bar的形状显示2. plot() 是连续函数,可以画一张连续的图,最一般最常用的画法。 plot(x)同样…
I am trying to allow users to enter an array of number such as [-13.62 12 4.5 6.06] inot an edit field to plot a stem plot. I do not know how to pass the array ain an edit field. Can someone assist please? Thank you,
How do I remove lines atached to each point in the STEM plot in MATLAB? There are many lines together so I cannot see the points properly. Thanks. 댓글 수: 0 댓글을 달려면 로그인하십시오. 답변 (2개) ...
Create separate stem plots in the axes by specifying the axes object as the first argument to stem. Get x = 0:25; y1 = exp(0.1*x); y2 = -exp(.05*x); tiledlayout(2,1) % Top plot ax1 = nexttile; stem(ax1,x,y1) % Bottom plot ax2 = nexttile; stem(ax2,x,y2) Modify ...
In this chapter, the discrete sequence plot in MATLAB is presented and described. In this regard, several examples and exercises for each section of the chapter are presented. The exercises that include writing the codes, executing them, and achieving the results need to be done by students to...
clc; clear all; close all; x = linspace(0,2*pi,60); a = sin(x); b = cos(x); plot(x,a+b) hold on stem(x,a) stem(x,b) hold off title('Linear Combination of Two Functions') xlabel('Time in \musecs') ylabel('Magnitude') legend('a+b','a = sin(x)','b = cos(x...
plot() 函数用于绘制连续函数图像,是Matlab中最为常用和基础的绘图方法。subplot(m,n,p) 函数用于在一个图形中创建多个子图,其中m表示行数,n表示列数,p表示子图的编号。每个子图可以独立绘制,并且都是连续的,使得多个图像可以同时在一个平面上展示。若需要获取subplot函数的详细帮助信息,可以在...
一、函数类型不同 stem画出来是离散函数,杆图。plot是连续函数。二、绘制的图形不同 在matlab中,stem函数用于绘制火柴梗图。stem英文有“(工具的)柄,把,杆,茎,(树)干,(叶)柄的意思。plot则是普通的连续曲线。
