Returns the number of elements in each dimension of an array.



An n-dimensional array of any type.



The number of elements in the array.

This output returns different data types, depending on the dimension of the array:

  • One-dimension—This output returns a 32-bit integer.
  • Multidimensional—This output returns a 1D array in which each element is a 32-bit integer that represents the number of elements in the corresponding dimension of array.

Representation of Array Dimensions in the Output Array

For multidimensional arrays, the order of elements in the output array corresponds to row-major order. Thus, the first dimension in the input array always corresponds to the last element in the output array. The following table shows how output array elements correspond to input array dimensions for a 4D array.

Element in Output Array Corresponding Input Array Dimension Index Name
1 4th Volume
2 3rd Page
3 2nd Row
4 1st Column
