## 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

    -->
    quit
