Is this a new feature of Matlab or an old feature that has been
removed? In Matlab R2007b:

>> a = 1:10 ;
>> a(1:)
??? a(1:)
        |
Error: Unbalanced or unexpected parenthesis or bracket.

>> a(:1)
??? a(:1)
       |
Error: Unexpected MATLAB expression.

I'm familiar with IDL using this sort of syntax and I've always
thought it made sense. In IDL you can even just use a negative index
e.g. a(1:-3) and it does what you would expect.
