Description

M

The median. If the input is a matrix, then the median of each column is returned in a vector.

Example

Find the median of the data set [1,2,3,4,5,7].

Syntax

M = Median([1,2,3,4,5,7])

Result

M = 3.5

Comments

If Data is a scalar, the result is that value.

If Data is a vector with an odd number of elements, the result is a scalar that is the element at the center of the ordered vector (element (N+1)/2, where N is the number of elements).

If Data is a vector with an even number of elements, the result is a scalar that is the average value of the two elements closest to the center of the ordered vector (elements N/2 and (N+1)/2, where N is the number of elements).
