## Saving a vector in a sub for-loop in the main loop

Hello,

I am trying to save the results obtained in the sub loop to the main loop but seems I am getting some errors; below is an example of what I need:

```values=zeros(1,3);
for x=1:3
result=zeros(1,10);
for y=1:10
equation1=rand; %just for simplicity
result(y)=equation1; %This is what I want to save in the main loop; in this case it would consist of 30 elements
end
equation2=sum(result);
values(x)=equation2;
end
```

Any ideas are appreciated!

`    result=zeros(10,3);`
```    for x=1:3
for y=1:10
equation1=.....
result(y,x)=equation1;
end
end```
`     values=sum(result,1);`

Dear Matt,

Many thanks for your quick answer- but it doesn't seem to work. I have even tried result(x,y)- same it gives different answers but the problem in both seems to be that the older values (first 10), are deleted when recording the new ones.

Beside- should I modify result=zeros(1,10); at the beginning as the vector now would consist of 30 elements?

note: I have edited my question so that equation1=rand; just for simplicity- if you just copy the code and paste it into Matlab, you would see the problem!

Thanks again and regards

Matt J

You will see in my version of the code that I already do initialize result to have 30 elements.
