# Simple Matlab program

## Simple Matlab program

(OP)
Experts, Looking for a matlab program.

Generates signal h(i) with 17 samples defined as

h(i) = i , for 0<=i<=8
h(i) = 16-i , for 9<=i<=16

for i=1:8
h(i)=1;
end
for i=9:16
h(i)=16-i;
end

Is this for school?

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.

### RE: Simple Matlab program

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

### RE: Simple Matlab program

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.

### RE: Simple Matlab program

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.

### RE: Simple Matlab program

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.

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