**NLENG(***matrix***)**

where *matrix* is a numeric or character matrix.

The NLENG function returns a single numeric value that
is the size in bytes of each element in *matrix*.
All matrix elements have the same size.
If the matrix does not have a value, then
the NLENG function returns a value of 0.
This function is different from the LENGTH
function, which returns the size of each element of
a character matrix, omitting the trailing blanks.

The following statement returns the value 7:

a=nleng({"ab " "ijklm ", "x" " "});
