I'm pretty sure the answer to this question is no but I'm hoping to be surprised. Is it possible to directly index a returned array without first assigning a variable? I created a simple trivial example below to explain what I mean.
Simple Example By variable assignment:
x = 1:10;
y = find( x>5 ); % y is a temporary variable
desired = y(1:2) % y1 is the desired matrix
Simple Example by Direct Index
x = 1:10;
desired = find( x>5 )[1:2] % 'suggested' code
To be clear the second line above is not meant to, nor does it work. I'm providing a comparison of working and theoretical code to suggest what I mean by 'direct index'.

No. This topic has been discussed many, many times on the newsgroup.

For this specific case:
desired = x(find( x>5,2,'first'))
For the more general case (i.e. not FIND)

Sean de is correct for the case given but I should have been more clear. I am looking for the general case, I arbitrarily chose find as an example of when this might be useful.
