Rootsumofsquares level
Y = rssq(X)
Y = rssq(X,DIM)
returns
the rootsumofsquares (RSS) level, Y
= rssq(X
)Y
, of the
input, X
. If X
is a row
or column vector, Y
is a realvalued scalar.
For matrices, Y
contains the RSS levels computed
along the first nonsingleton dimension. For example, if Y
is
an NbyM matrix with N>1, Y
is a 1byM row
vector containing the RSS levels of the columns of Y
.
computes
the RSS level of Y
= rssq(X
,DIM
)X
along the dimension, DIM
.

Real or complexvalued input vector or matrix. By default,
