如何在单个图中使用for循环matlab绘制多个函数

Question

我想绘制带有阴影效果的路径损耗自由空间传播模型。对于那个路径损失指数n我想通过一个for循环来改变它的值，并且想要在一个图上显示所有不同的图。 所以，到目前为止我使用下面的代码，

clc 
clear all 

c = 3*10^8; %in light speed in free space 
fc = 28*10^9; % 28Ghz 
lamda=c/fc; 
do = 5; % free space refernce distance 1m 
PLdo = 20*log(4*pi*do/lamda); 
%%in dB% Log-distance path loss model 
%%path losss PL(d) at a particular location is random from paper 

for n = 2:5 
d = 1:0.2:200; %T-R separation in meter 
PLd = PLdo + 10*n*log(d./do) + 6.9*randn(1,length(10*n*log(d./do))); 
end 

figure 
dis_dB = 10*log(d); 
plot(dis_dB, PLd, '*') 

但是，可能是其呈现一个情节。如下图所示， enter image description here

如何能够基于n

Answer 1

使用hold on不同的价值观我呈现不同的曲线：

clc 
clear all 

c = 3*10^8; %in light speed in free space 
fc = 28*10^9; % 28Ghz 
lamda=c/fc; 
do = 5; % free space refernce distance 1m 
PLdo = 20*log(4*pi*do/lamda); 
%%in dB% Log-distance path loss model 
%%path losss PL(d) at a particular location is random from paper 

for n = 2:5 
    d = 1:0.2:200; %T-R separation in meter 
    PLd = PLdo + 10*n*log(d./do) + 6.9*randn(1,length(10*n*log(d./do))); 
    dis_dB = 10*log(d); 
    plot(dis_dB, PLd, '*'), hold on 
end
