nanmedian

median of the values of a numerical vector or matrix

Syntax

m=nanmedian(x)
m=nanmedian(x,'r') (or m=nanmedian(x,1))
m=nanmedian(x,'c') (or m=nanmedian(x,2))

Arguments

x

real or complex vector or matrix

Description

For a vector or a matrix x, [m]=nanmedian(x) returns in the vector m the median of the values (ignoring the NANs) of vector x.

[m]=nanmedian(x,'r') (or, equivalently, [m]=nanmedian(x,1)) are the rowwise medians. It returns in each position of the row vector m the medians of data (ignoring the NANs) in the corresponding column of x.

[m]=nanmedian(x,'c') (or, equivalently, [m]=nanmedian(x,2)) are the columnwise medians. It returns in each position of the column vector m the medians of data (ignoring the NANs) in the corresponding row of x.

In Labostat, NAN values stand for missing values in tables.

Examples

x=[0.2113249 %nan 0.6653811;0.7560439 0.3303271 0.6283918]
m=nanmedian(x)
m=nanmedian(x,1)
m=nanmedian(x,2)
