Use flg
to override the defaults that
govern which elements symerr
compares and how
symerr
computes the outputs. The values of
flg
are 'overall'
,
'columnwise'
, and 'rowwise'
. The table
below describes the differences that result from various combinations of inputs. In
all cases, ratio
is number
divided by the
total number of elements in y
.
Comparing a TwoDimensional Matrix x with Another
Input y
Shape of y  flg  Type of Comparison  number 

Twodim. matrix  'overall' (default)  Element by element  Total number of symbol errors 
'columnwise'  m^{th} column of
x vs.
m^{th} column of
y
 Row vector whose entries count symbol errors in each column

'rowwise'  m^{th} row of
x vs.
m^{th} row of
y
 Column vector whose entries count symbol errors in each row

Column vector  'overall'

 Total number of symbol errors 
'columnwise' (default)  y vs. each column of x
 Row vector whose entries count symbol errors in each column
of x

Row vector  'overall'  y vs. each row of x
 Total number of symbol errors 
'rowwise' (default)  y vs. each row of x
 Column vector whose entries count symbol errors in each row
