median (DataMatrix) - Return median values in DataMatrix object

Syntax

Input Arguments

DMObj	DataMatrix object, such as created by DataMatrix (object constructor).
Dim	Scalar specifying the dimension of DMObj to calculate the medians. Choices are: 1 — Default. Returns median values for elements in each column. 2 — Returns median values for elements in each row.
IgnoreNaN	Specifies if NaNs should be ignored. Choices are true (default) or false.

Output Arguments

Med	Either of the following: Row vector containing the median values from elements in each column in DMObj (when Dim = 1) Column vector containing the median values from elements in each row in DMObj (when Dim = 2)

Description

Med = median(DMObj) returns the median values of the elements in the columns of a DataMatrix object, treating NaNs as missing values. Med is a row vector containing the median values for elements in each column in DMObj.

Med = median(DMObj, Dim) returns the median values of the elements in the columns or rows of a DataMatrix object, as specified by Dim. If Dim = 1, returns Med, a row vector containing the median values for elements in each column in DMObj. If Dim = 2, returns Med, a column vector containing the median values for elements in each row in DMObj. Default Dim = 1.

Med = median(DMObj, Dim, IgnoreNaN) specifies if NaNs should be ignored. IgnoreNaN can be true (default) or false.
