Can someone explain this Code?

Hi,

I have the following code on MATLAB, i don't know is it working properly or not. Would you help me to understand the complete content of code and how to make it work right?

clear, clc 
for i=1:2:5 
for j=1:2:5 
x=x+3 
xt=[xt x];  
y=y+x 
yt=[yt y]; 
end 
end

Maybe you could tell us what the code is supposed to do?

Hello,

Here is what i achieved to help you understand your algorithm. You can run the code and track how variables evolve through the execution.

"clear" and "clc" are just used to clean the workspace variables and the command window before your code execution.

clear
clc

%initialize x,y,xt,yt
x=0
xt=0
y=0
yt=0

%Here you enter the main loop
for i=1:2:5
    disp(['increment i=',num2str(i)])
    for j=1:2:5
        disp(['increment j=',num2str(j)])
        x=x+3 
        xt=[xt x]
        y=y+x
        yt=[yt y]
    end
end

%final values
x_final=x
xt_final=xt
y_final=y
yt_final=yt
