all check whether all elements of a boolean vector are true

## Declaration

bool `all` bvec x

## Parameters

x

  Specifies the vector to be tested for truth.

## Description

`any` returns true if all elements of x are true and false otherwise. It is functionally equivalent to:

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