## < Less than

Compares each element in the left-hand argument with the corresponding element in the right-hand argument. If an element in the left-hand argument is less than the corresponding right-hand element, the result of that comparison is 1. Otherwise it is 0. (This operation is affected by ŒCT, the comparison tolerance)

           0 0 0 1                        the corresponding element in a vector of

                 ¯3 < ¯4                 (Compares negative numbers. The number
           0                              nearer 0 is considered the greater.)

                 8 < 2+2+2+2             (The right argument is evaluated
           0                              before the comparison is made)
