MATLAB: To find the meaning of this code

meaning of code for circuit analysis

MatLab Programming:-
%% Main File
clc;
clear all;
close all;
 [t,x]=ode45(@rlcckt,[0 1],[0 0]); 
plot(t,x(:,1),'m');
 hold on plot(t,x(:,2),'b'); 
legend('x1','x2'); 
 
%% Function File 
function dx=rlcckt(t,x) 
dx = zeros(2,1); 
Vin=5; 
R=5; 
C=10;
 L=0.5;
 dx(1)=x(2); 
dx(2)=(Vin/L)-((R/L)*x(2))-((1/L*C)*x(1));
end

Best Answer

It solves two differential equations and plots the solution for them.
 [t,x]=ode45(@rlcckt,[0 1],[0 0]);
ode45 integrates the system of differential equations (the ODEs are specified in function rlcckt) from t=0 to t=1 ([0 1]) with inital conditions [0 0].

plot(t,x(:,1),'m');
 hold on plot(t,x(:,2),'b'); 
legend('x1','x2');
Here, you are plotting the two solutions in the same figure with time in the x axis.
