You left h(0), that is what I am looking for.

Thanks

It looks like the 3 micro seconds it took to give those basic 2 loops was 3 microseconds too much.

If you need a 0 index, I suggest using Python instead of Matlab.

Python is good. But, it's no Matlab. There are other ways to get around the "0" index. This is IMO

There's been more debate about zero-based indexing than there has been about the existence of God.

Actually, Matlab *can* use zero-based indices. They are indicated with
an (unfortunately rather low precedence and rather obscurely
documented) prefix operator "1+", i.e.

a(1+(0:m))

Actually, it doesn't seem so obscure to me.
1+(0:2)
evaluates to
1 2 3
as expected. We are just converting the index we prefer to see (0:...) to the index matlab wants (1:...).

Maybe there is some subtlety that I'm missing.

Ummm, I was being facetious since he was obviously a student poster required to program something in Matlab.

But I do prefer Python due to 1) I work for a small company that won't shell out the cash for Matlab and 2) the existence of tools like pythonxy.

Don't worry Brad, I lol'd when I read your post. I was right there with you.

I meant no offence Brad. I agree with your points.

As for the "a(1+(0:m))" this is just adding 1 to the original index. It works, does it really matter if we end at m+1 instead of m? I would imagine in most cases no.

There's been more debate about zero-based indexing than there has been about the existence of God.

I'm with you on this. So let's leave it to God then
