standard deviation (ignoring the NANs).
s = nanstdev(x) s = nanstdev(x, orientation)
real or complex vector or matrix
index of the dimension along which the nanstdev is computed. It can be either
"*"
(default), "r"
or
"c"
real or complex scalar or vector
This function computes the standard deviation of the
values of a vector or matrix x
(ignoring the
NANs).
For a vector or a matrix x
, s = nanstdev(x)
or s = nanstdev(x, "*")
returns in the scalar s
the standard deviation
of all the entries of x
(ignoring the NANs).
s = nanstdev(x, 'r')
(or, equivalently,
s = nanstdev(x, 1)
) is the rowwise standard deviation.
It returns in each entry of the row vector s
the
standard deviation of each column of x
(ignoring
the NANs).
s = nanstdev(x, 'c')
(or, equivalently,
s = nanstdev(x, 2)
) is the columnwise standard
deviation. It returns in each entry of the column vector
s
the standard deviation of each row of x
(ignoring the NANs).
In Labostat, NAN values stand for missing values in tables.
