Problem with reaching specific values of an array or matrix

Hello. I have a for loop, for each value of counter, I want to find the relevent raw value when rs==1 or ep==1 from various excel files.

If rs==1, I want it to write t_c's relevant value corresponding its raw value.

If ep==1, I want it to write t_c's relevant value corresponding its raw value + 1.

However, when I consider raw value + 1, I get zero values (even without if loop). I do not understand why this happens so? When I try to find its relevant value for raw value, I get true values (without the if loop). I would be happy if I solved this question.Thank you. :)

Below is a part of my code:

ep=mydata(:,1);
counter=mydata(:,2);
rs=mydata(:,3);
t_c=mydata(:,4);

t=[]; 
raw=[];
for n=0:4
    f=1;
    raw(f)=find((counter == n)  & ((rs==1) | (ep==1)))
    y(f)=raw(f)+1
    
    if (rs==1)
        te(f)=t_c(raw(f))
    else (ep==1)
        te(f)=t_c(y(f))       
    end
    
    t=[t te(f)]
    C=table(t);  
    f=f+1;
end

There are no "if loops" in any programming language I know.

What does this mean: "when I consider raw value + 1, I get zero values (even without if loop)"

This part is useless:

for n = 0:4
    f = 1;    % f is set to 1
    ...
    f = f+1;  % Now f is 2 - but reset in the next iteration
end

I am sorry I misused the word loop. I mean if statements.

Lets think of it like this. I have an excel table. What I am trying to do is finding y values from the found intersections for each n value :

raw(f)=find((counter == n)  & ((rs==1) | (ep==1)))

After finding y (raw) values, I am trying to find relevant x values for t_c. We may think of it like a function.

For relevant coloums having rs==1, I can easily find x values for t_c by using the obtained y (raw) values.

But for relevant coloums having ep==1, I need to find the corresponding x value by using y+1 value. I am not able to obtain this value, I get zero values. I tried to do this using if statements.

I hope my problem is more understandable now. Thank you. :)

Give us a sample dataset and show us what you're trying to produce; I get lost in the verbal description -- it's not at all clear what you really mean by "for relevant coloums having ep==1, I need to find the corresponding x value by using y+1 value. "

This line looks strange:

else (explode==1)    

I guess you mean elseif.

Thank you so much for all the comments and suggestions. I have solved the problem in another way. I used another variable from the excel file in if else statement. It did not give any error and produced relevant x values from raw-y values correctly. :)

Have a good day.

I'd suggest posting your final code as an Answer, then -- you can Accept your own. Serves to let folks know the problem is sovled if nothing else.

Ok, I have just posted it. Thank you so much for the quick replies. :)

This is the finalized version of the code. It is working as expected. Thank you for all the help. :)

ep=mydata(:,1);
counter=mydata(:,2);
rs=mydata(:,3);
t_c=mydata(:,4);
a=mydata(:,5);
t=[]; 
raw=[];
for n=0:4
    f=1;
    raw(f)=find((counter == n)  & ((rs==1) | (ep==1)));
    y(f)=raw(f)+1;
    
    if (a==0)
        te(f)=t_c(raw(f));
    else 
        te(f)=0;      
    end
    
    t=[t te(f)]
    C=table(t);  
    f=f+1;
end
