I am trying to plot kinetic energy as a function of time. I am using fplot inside a foor loop which results in two errors and a warning.
clear; clcV = 5000;d = 0.5e-2;B = 1; q = 1.6e-19;m = 1.7e-27;% T = 2pi/omega
% q V = 0.5 m v^2
% m v^2 = 2 q V
% v = sqrt(2 q V / m)
% q v B = m v^2 / r
% r = 2 V / v B
T(1) = 0;r(1)= 2*V/(sqrt(2*q*V/m)*B);n=1;while r(n)<5e-2 V = n*5000; r(n+1)= 2*V/(sqrt(2*q*V/m)*B); T(n+1) = T(n) + (6.67588e-8)/2; n=n+1;end%2*V/(sqrt(2*q*V/m)*B)
n%plot(T, r, '.-'), legend('Radius')
%xlabel('Time [s]')
%ylabel('Radius [m]')
V=5000;t=zeros(1,n);t(1)=1.03077640640442e-08;for i=1:n vi=sqrt(2*(i-1)*q*V/m); vf=sqrt(2*i*q*V/m); vm=(vf-vi)/2; t(i+1)=t(i)+d/vm; ti=t(i); Ti=T(i); tf=t(i+1); Tf=T(i+1); fplot(@(x) (q.*V./ti).*x,[Ti Ti+tf],'b') hold on fplot(@(x) 0.5.*m.*vm.^2,[Ti+tf Tf],'b') endhold off
So the errors occurs at the end of the code when I'm trying to plot the functions.
If you have any other suggestions please tell as this code probably looks quite bad.
