Hello,
I am having a problem with my for loop,
I want it to generate every possible plot for r between 2.1 and 4 with 0.1 increment,
what am I doing wrong
'I am a beginner
clc
clear
% first we should note that this is a log-log plot
% Let's introduce k first
k = logspace(0, 4, 100); %connectivity of a vertix
PK1= k.^(-2.9+0.1); % for gamma equal 2.9-0.1
PK2= k.^(-2.9-0.1); % for gamma equal 2.9+0.1
for r=2.1:4
PK3=k.^(-r); %for gamma changing between 2.1 and 4
loglog(k,PK3,'s')
hold on
loglog(k,PK1,'s') % plot with squares that describe gamma=2.9-0.1
loglog(k,PK2,'o') %plot with rounds that describe gamma=2.9+0.1
loglog(mean(k),'--', 'LineWidth',5)
hold off
r=r+0.1;
end
