Program:

Comments:

 

 

m →ARRY

Combines all the medians into an m-element vector.

s STOΣ

Restores ΣDAT to its previous value.

»

Ends the defining procedure.

`OMEDIAN K

Stores the program in MEDIAN.

 

 

 

Checksum: # 256d

Bytes: 140

Example: Calculate the median of the following data.

1812

4 7

3 2

111

3148

2017

There are two columns of data, so MEDIAN will return a two-element vector.

Enter the matrix.

Expanding and Collecting Completely

This section contains two programs:

MULTI repeats a program until the program has no effect on its argument.

EXCO calls MULTI to completely expand and collect an algebraic.
