How to manipulate the index of the for loop

Hi,

I have to change the index of the for loop inside the loop only. Something like this,

 for i1 = 1:10

   if i1 =4

     i1 = 6;

   end

 end

But I am not able to do this. Can some one help me in doing this.

Thanks,

Mallikarjun

Of course "you are able to do this". You can write it down and it is valid Matlab code, such that it will run (except for the == operator in the if condition). But I can guess, that you want to do something else. Then please explain explicitly, what you want and what you get. Relying on the power to guess problems and intentions is a bad idea in a forum.

Answer 1

[Azzi Abdelmalek]

for i1 = 1:10
 if i1==4
   i1 = 6;
 end
end

when i1==4 you set i1 to 6 ; the next iteration i1 will be equal to 5

%or

v=1:10;
v(v==4)=6;
for i1 = v
 %do
end

A WHILE loop would work:

i1 = 1;
while i1 <= 10
  if i1 == 4
    i1 = 6;
  end
  i1 = i1 + 1;
end
