Examples

ROW a=[3, 5, 1]
| EVAL median_a = MV_MEDIAN(a)

a:integer	median_a:integer
[3, 5, 1]	3

If the row has an even number of values for a column, the result will be the average of the middle two entries. If the column is not floating point, the average rounds down:

ROW a=[3, 7, 1, 6]
| EVAL median_a = MV_MEDIAN(a)

a:integer	median_a:integer
[3, 7, 1, 6]	4
