nanmedian
median of the values of a numerical vector or matrix
Syntax
m = nanmedian(x) m = nanmedian(x, orientation)
Arguments
- x
real or complex vector or matrix
- orientation
index of the dimension along which the nanmedian is computed. It can be either
- a character
"*"
(default),"r"
or"c"
- a positive integer: 1 or 2. 1 is equivalent to "r" and 2 is equivalent to "c".
- a character
- m
real or complex scalar or vector
Description
For a vector or a matrix x
,
m = nanmedian(x)
or 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)
