Description
Returns the norm of each column of x where x is a real,
double-precision, or complex matrix.
The return value is a row vector
with the same number of columns as x.
If x is complex,
the return value is double-precision,
otherwise the return value has the same type as x.
The jth element of the return value is
--------------------------------------
/ 2 2 2
\ / | x | + | x | + ... + | x |
\/ 1,j 2,jn,j where n is the number of rows in the matrix x.
Example
If you enter
x = [{1., 1.}, {3., 4.}]
colnorm(x)
O-Matrix will respond
[ 1.41421 , 5 ]
