Index exceeds matrix dimensions

I have the code below, but I don't understand why it is that my index exceeds matrix dimensions.

i=1;
for min=0:60:240
  hour(i)=min(i+1)/60;
  i=i+1;
end

I also tried the code below to work around the error, but I am still getting it. Any takers?

min=0:60:240;
for i=1:length(min)
  hour(i)=min(i+1)/60;
end

I fixed your formatting but request you read this so you know how to do it yourself next time: http://www.mathworks.com/matlabcentral/answers/13205-tutorial-how-to-format-your-question-with-markup

min() is a built in function. You've done something very bad by using it as your variable name.

But since you've destroyed the min function, it's now a variable with length of length(min). So what index are you at when i = length(min)? You have min(length(min)+1) which is past the end of your badly-named variable. Just say:

minIndex = 0:60:240;
for i=1:length(minIndex)
  hour(i) = minIndex(i)/60;
end

Or

minIndex = 0:60:240;
for i = minIndex 
  hour(i) = i / 60;
end

Or, even better

minIndex = 0:60:240;
hour = minIndex / 60;
