length
length of object
Calling Sequence
n=length(M)
Arguments
- 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
.
WARNING : length of a sparse matrix returns the max of dimensions and not the product of the dimensions. (example : length(sparse(eye(12,2))) returns max(12,2) and not 24)
please use size(...,'*') with sparse matrix.
Examples
length([123 ; 456 ]) length(['hello world',SCI])
