any
any(X) returns true if any of vector's X elements are non zero.
If X is a matrix a logical row vector is returned with the i-th element indicating whether any of X i-th column elements are non zero or not.
any(X,dim) allows specifying dimension along which to test.

Examples
> any([0 0 2]) [ans:true]
> any([0 0 0]) [ans:false]
> any([1 2 0; 2 2 0; 1 0 0])# 1 1 0
> any([1 2 0; 2 2 0; 1 0 0],2)# 1 1 1
