## 1st axis expand

The expansion function applies by default to the last axis, unless used in conjunction with the axis operator, [] (remember this is affected by IO). The first axis expansion function, , applies by default to the first axis, but otherwise behaves in the same way as the expansion function.

                 TABLE  2 5½Ό10
                 1 0 1  TABLE           (Using the other axis, the
           1  2  3  4  5                  same as 1 0 1\[1]TABLE)
           0  0  0  0  0
           6  7  8  9 10
