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)
