Index exceeds array bounds

Hello All,

I wanted to ask if I can write some code to overcome the error resulting from index exceeding array bounds. For example, in the code below, is there anyth9ng that can be done to return a result x(11) = 0 instead of getting an error?

    x=[1:10]
    x(11)

Thanking you in advance.

Context: My issue is the array has 10 elements but I have several boundary condition equations trying go access element 11 (and element 0 as well). Hence I'm getting an error. So far I've been managing to avoid the error by modifying each single equation to account for the boundary condition. However I'm wondering if there's a general code I can write to get a value of 0 for indices outside the array boundaries.

You misunderstood me. I'll try to add more to the question to make it clearer.

    x=[1:10] ; 
    idx = 11 ; 
    if idx>length(x)
        x(idx) = 0 ;
    end
    x(11)

Amazing. Thank you
