=<T:!
Puts the row elements on the
stack. Drops the index list { n }.
Makes an n-element list.
Sorts the list and calculates its
median.
Moves the median to the proper
stack level.
Increments j and repeats the loop.

Combines all the medians into an
m-element vector.
Restores

DAT to its previous
value.
Ends the defining procedure.

`OMEDIAN K
Stores the program in MEDIAN.
Checksum: # 50773d
Bytes: 136
Example: Calculate the median of the following data.
18 12
47
32
11 1
31 48
20 17
There are two columns of data, so MEDIAN will return a two-element vector.
Enter the matrix.
