run the for loop only once Matlab

Hi everybody, i want to know if its possible to run the for-loop only once.

      total_Route = zeros(4,4);

        for i=1:4

         total_Route(i,1)=Distance_Traveled_CM;
         total_Route(i,2)=Hauptantrieb_Verbrauchte_Energie_CM;
         total_Route(i,3)=Nebenaggregate_Verbrauch_Real_CM;
         total_Route(i,4)= i;

        Total_Distance_Traveled_CM = sum(total_Route(:,1));
        set(handles.edit3, 'string',Total_Distance_Traveled_CM);

        Total_Hauptantrieb_Verbrauchte_Energie_CM=sum(total_Route(:,2));
        set(handles.edit4, 'string',Total_Hauptantrieb_Verbrauchte_Energie_CM);

        Total_Nebenaggregate_Verbrauch_Real_CM=sum(total_Route(:,3));
        set(handles.edit5, 'string',Total_Nebenaggregate_Verbrauch_Real_CM);

        %%Index
        set(handles.edit15, 'string',i);

after the running this code, "i" is then at the end 4 and the for-loop will be runs 4 times

i want to run the for-loop only once and "i" should be incremented after each pass

I am thankful for every help

If you want to run it once, then don't use a for loop, to increment ii, use

ii=mod(ii,4)+1

don't use i, it's used to represent complex numbers

Thank u @Azzi for the quick response.

Heey Azzi

with Which value u would initialise i at the beginning, because this code is not working

   ii = 0;
   ii=mod(ii,4)+1;
%i is in the case always 1

[Azzi Abdelmalek]

if isempty(ii)
ii = 0;
end
ii=mod(ii,4)+1;

im using this code in the Gui-Window, and my programm still giving me this feedback:

Variable i is might be used befor it is defined. should ii write the below code in the Callback window ?

   if isempty(ii)

    ii = 0;

     end

I don't know how many files you are using! are you using functions?

[Azzi Abdelmalek]

Try this

id=whos('ii')
if isempty(id)
  ii=0
end
ii=ii+1

Hallo Azzi,

im using normal scripts, i creatd a Matrix with 4×4 Element with the Goal to save the results off each my Variable in a element off my Matrix.

Example:

the first pass: ii=0 ->> Distance_Traveled 900(first element (1,1)) the gui will take the sum of the first column wich (900+0+0+0) and write it in a static test

the second pass i=1-->Disantace traveled(2,1) 800 the gui will take the sum of the first column wich (900+800+0+0) and write it in a static test and same thing should happen with the other column

i want through the gui every time to write the summe of a column of my Matrix and write it in a satic text box. i

 hope, u catch what i mean

[Alex]

i think the Problem is that ii doesnt keep his last Value

 id=whos('ii')
if isempty(id)
  ii=0
end
ii=ii+1
because with this code will be ii always 1.

Why not simply replace this line

for i=1:4

with this line:

i = 1;

It will do the code just once since it won't even be in a loop.
