## SIZE Size of a Variable

Section: Inspection Functions

### Usage

Returns the size of a variable. There are two syntaxes for its use. The first syntax returns the size of the array as a vector of integers, one integer for each dimension[d1,d2,...,dn] = size(x)

The other format returns the size of `x`

along a particular
dimension:

d = size(x,n)

where `n`

is the dimension along which to return the size.

### Example

--> a = randn(23,12,5); --> size(a) ans = 23 12 5

Here is an example of the second form of `size`

.

--> size(a,2) ans = 12
