## LENGTH Length of an Array

Section: Inspection Functions

### Usage

Returns the length of an array`x`

. The syntax for its use
is
y = length(x)

and is defined as the maximum length of `x`

along any of its
dimensions, i.e., `max(size(x))`

. If you want to determine the
number of elements in `x`

, use the `numel`

function instead.

### Example

For a`4 x 4 x 3`

matrix, the length is `4`

, not `48`

, as you
might expect.
--> x = rand(4,4,3); --> length(x) ans = 4
