Calling Sequence
s=center(x) s=center(x,'r') or s=center(x,1) s=center(x,'c') or s=center(x,2)
Arguments
x: real or complex vector or matrix
Description
This function computes s
, the centred version of
the numerical matrix x
.
For a vector or a matrix x
, s=center(x)
returns in the (i,j)
coefficient of the matrix s
the value (x(i,j)-xbar)
, where xbar
is
the mean of the values of the coefficients of x
.
s=center(x,'r')
(or, equivalently,
s=center(x,1)
) is the rowwise center reduction of the
values of x
. It returns in the entry s(i,j)
the value (x(i,j)-xbarv(j))(j)
with xbarv(j)
the mean of the values of the j
column.
s=center(x,'c')
(or, equivalently,
s=center(x,2)
) is the columnwise center reduction of
the values of x
. It returns in the entry
s(i,j)
the value (x(i,j)-xbarh(i)))
with
xbarh(i)
the mean of the values of the i
row.
Examples
x=[0.2113249 0.0002211 0.6653811; 0.7560439 0.3303271 0.6283918] s=center(x) s=center(x,'r') s=center(x,'c')
