i would like to use the loop for that looks for the maximum of a vector and its position without using the 'max.can anyone help me ?

i had tried this, but i doesn't give me what i want,

maxi=x(1);
for i=1:length(x)
    %
    if x(i)>maxi
        maxi=x(i);
        indice=i;
    else
        maxi=maxi;
        indice=i;
    end
end

you have got it almost right, you just need to put them inside the loop. I'll give you some tips to work further.

• first assign the first value of the vector to maxi and set indice to 1.

 maxi = x(1);
 indice = 1;

• then loop through number of elements of x starting from 2 (since we have assigned first value of x to maxi),

 for k=2:numel(x)
  if(x(k)>maxi)
    %and the remainig logic
  end %end of if
 end %end of for

• in your if else condition, you do not have to assign maxi=maxi for the else case, you can simply write continue;. This will continue to the next iteration.

thank you Mr,Kl, , i had got this,

 maxi=x(1);indice=1;
for i=2:length(x)
if x(i)>maxi
maxi=x(i);
indice=i;
end
end
i think, that's the right way, thank you for your tips.
