Non-Integer For-Loop

I have what I hope is a relatively simple question. I am trying to construct a for loop over a value h from 0 to 1 with loop indices of 0.1 where there value of h will be plugged directly into an expression in the loop.

I tried the following:

dt = 0.1;

t = 0:dt:1;

nt = length(t);

%--------

for h = 1 : nt

Any assistance would be appreciated.

Hi Christopher

for h = 0:.1:1

works, although with the interval expressed in floating point, you have to be careful.

    for h = (0:10)/10

is safer, since the increment is an integer. If you are plugging the resulting value of h into some expression within the for loop there will be no problems. But if you are comparing h to some other value computed in the for loop, a la

        if h == [some computed value]

you of course have to beware of floating point comparisons that might disagree in the 16th decimal place and give you an unwanted answer.
