length(1)

NAME
length - length of object

CALLING SEQUENCE
n=length(M)

PARAMETERS

M   : matrix (usual or polynomial or character string) or list

n   : integer or integer matrix

DESCRIPTION
For usual or polynomial matrix n is the integer equal to number of rows times number of columns of M. (Also valid for M a boolean matrix)

For matrices made of character strings (and in particular for a character string) length returns in n the length of entries of the matrix of character strings M.

The length of a list is the number of elements in the list (also given by size).

length('123') is 3. length([1,2;3,4]) is 4.
