Indexing question

[Roberto Hernandez]

Hi all,

When I need to find the first element in a vector that meets a certain 
condition I use a combination of "find" and "min".

For example:

a = 0:100;

If I need the first element that is > 20:

min(find(a > 20))

Is there a built-in function that does this? If so I haven't been able 
to find it.

TIA,

Roberto
