Check whether any element of a boolean vector is true.


bool any( bvec x );


x - Specifies the vector to be tested for truth.


 any returns true if any element of x is true and false otherwise. It is functionally equivalent to:

   bool any(bvec x) {     // bvec can be bvec2, bvec3 or bvec4
       bool result = false;
       int i;
       for (i = 0; i < x.length(); ++i) {
           result |= x[i];
       return result;
