Working with for loop

Hi,

In my following code I want my final result ( final_delay) without skipping any index. Currently it skipping 4 index because of this line (i_value= 1:4:len). But I dont want to skip this index for my final result. How can I do that.

Thank you so much for your time and considerations.

data1=rand(1,1000)
data2=rand(1,1000)
data3=rand(1,1000)

len=200;
time=zeros(1,len)
trigger=3
for i_value= 1:4:len

       delay1=data1(i_value)
       delay2=data1(i_value+1)
      delay_1=(delay1+delay2)/2 

       delay3=data2(i_value)
       delay4=data2(i_value+1)
       delay_2=(delay3+delay4)/2

       RTT_1=data2(i_value+2)+data3(i_value)+data1(i_value+2)
       final_delay(i_value)=  abs(RTT_1-delay_1-delay_2)        
end

Illustrate with an example and the desired result.

In the picture, this is my final result. But here its skipping 3 index as zero, but I want to keep that values. How can I do that?

Yet again you forgot to attach how the expected result should look like. Paste it as a text , screenshot is not useful.

I_values=1:4:len;

final_delay=nan(1,numel(I_values)); %PRE-ALLOCATE!!!!!!

for k=1:numel(I_values)
    
       i_value=I_values(k);% Matt J inserted
    
           delay1=data1(i_value)
           delay2=data1(i_value+1)
           delay_1=(delay1+delay2)/2 
           delay3=data2(i_value)
           delay4=data2(i_value+1)
           delay_2=(delay3+delay4)/2
           RTT_1=data2(i_value+2)+data3(i_value)+data1(i_value+2)
       
       final_delay(k)=  abs(RTT_1-delay_1-delay_2)  %Matt J edited

Thank you so much, yes, I want this. We are deleting the null index, right?

[Matt J]

We are not deleting anything, just filling a smaller vector.
