Format
----------------
.. function:: orders = getorders(a)

    :param a: data
    :type a: N-dimensional array, matrix, sparse matrix, string or string array

    :return orders: the sizes of the dimensions of the array.

    :rtype orders: Nx1 vector of orders

Examples
----------------

Example 1
+++++++++

::

    // Allocate a 5x100x3 dimensional array with each element equal to 0.
    a = arrayinit(5|100|3, 0);

    // Find the size of the dimensions in 'a'
    orders = getorders(a);

After the code above:

::

    orders =   5
             100
               3

Example 2
+++++++++

::

    // Create 121x4 random matrix
    x = rndn(121, 4);

    // Get the number of rows and columns of the matrix
    dims = getorders(x);

After the above code, *dims* should equal:

::

    121
      4
