  - getShort
```
short getShort(long... coordinates)
```
    Returns the short value of the scalar found at the given coordinates.
    To access the scalar element, the number of coordinates provided must be equal to the number of dimensions of this array (i.e. its rank). For example:
```
  ShortNdArray matrix = NdArrays.ofShorts(shape(2, 2));  // matrix rank = 2
  matrix.getShort(0, 1);  // succeeds, returns 0.0f
  matrix.getShort(0);  // throws IllegalRankException

  ShortNdArray scalar = matrix.get(0, 1);  // scalar rank = 0
  scalar.getShort();  // succeeds, returns 0.0f
 
```
    Parameters:
    
    coordinates - coordinates of the scalar to resolve
    
    Returns:
    
    value of that scalar
    
    Throws:
    
    IndexOutOfBoundsException - if some coordinates are outside the limits of their respective dimension
    
    IllegalRankException - if number of coordinates is not sufficient to access a scalar element
  - setShort
```
ShortNdArray setShort(short value,
                      long... coordinates)
```
    Assigns the short value of the scalar found at the given coordinates.
    To access the scalar element, the number of coordinates provided must be equal to the number of dimensions of this array (i.e. its rank). For example:
```
  ShortNdArray matrix = NdArrays.ofShorts(shape(2, 2));  // matrix rank = 2
  matrix.setShort(10.0f, 0, 1);  // succeeds
  matrix.setShort(10.0f, 0);  // throws IllegalRankException

  ShortNdArray scalar = matrix.get(0, 1);  // scalar rank = 0
  scalar.setShort(10.0f);  // succeeds
 
```
    Parameters:
    
    value - value to assign
    
    coordinates - coordinates of the scalar to assign
    
    Returns:
    
    this array
    
    Throws:
    
    IndexOutOfBoundsException - if some coordinates are outside the limits of their respective dimension
    
    IllegalRankException - if number of coordinates is not sufficient to access a scalar element
  - slice
```
ShortNdArray slice(Index... coordinates)
```
    Description copied from interface: NdArray
    Creates a multi-dimensional view (or slice) of this array by mapping one or more dimensions to the given index selectors.
    Slices allow to traverse an N-dimensional array in any of its axis and/or to filter only elements of interest. For example, for a given matrix on the [x, y] axes, it is possible to iterate elements at y=0 for all x.
    Any changes applied to the returned slice affect the data of this array as well, as there is no copy involved.
    Example of usage:
```
    FloatNdArray matrix3d = NdArrays.ofFloats(shape(3, 2, 4));  // with [x, y, z] axes

    // Iterates elements on the x axis by preserving only the 3rd value on the z axis,
    // (i.e. [x, y, 2])
    matrix3d.slice(all(), all(), at(2)).elements(0).forEach(m -> {
      assertEquals(shape(2), m); // y=2, z=0 (scalar)
    });

    // Creates a slice that contains only the last element of the y axis and elements with an
    // odd `z` coordinate.
    FloatNdArray slice = matrix3d.slice(all(), at(1), odd());
    assertEquals(shape(3, 2), slice.shape());  // x=3, y=0 (scalar), z=2 (odd coordinates)

    // Iterates backward the elements on the x axis
    matrix3d.slice(flip()).elements(0).forEach(m -> {
      assertEquals(shape(2, 4), m);  // y=2, z=4
    });
 
```
    Specified by:
    
    slice in interface NdArray<Short>
    
    Parameters:
    
    coordinates - index selectors per dimensions, starting from dimension 0 of this array.
    
    Returns:
    
    the element resulting of the index selection
  - get
```
ShortNdArray get(long... coordinates)
```
    Description copied from interface: NdArray
    
    Returns the N-dimensional element of this array at the given coordinates.
    Elements of any of the dimensions of this array can be retrieved. For example, if the number of coordinates is equal to the number of dimensions of this array, then a rank-0 (scalar) array is returned, which value can then be obtained by calling `array.getObject()`.
    Any changes applied to the returned elements affect the data of this array as well, as there is no copy involved.
    Note that invoking this method is an equivalent and more efficient way to slice this array on single scalar, i.e. array.get(x, y, z) is equal to array.slice(at(x), at(y), at(z))
    
    Specified by:
    
    get in interface NdArray<Short>
    
    Parameters:
    
    coordinates - coordinates of the element to access, none will return this array
    
    Returns:
    
    the element at this index
  - set
```
ShortNdArray set(NdArray<Short> src,
                 long... coordinates)
```
    Description copied from interface: NdArray
    Assigns the value of the N-dimensional element found at the given coordinates.
    The number of coordinates provided can be anywhere between 0 and rank - 1. For example:
```
  FloatNdArray matrix = NdArrays.ofFloats(shape(2, 2));  // matrix rank = 2
  matrix.set(vector(10.0f, 20.0f), 0);  // success
  matrix.set(scalar(10.0f), 1, 0); // success
 
```
    Specified by:
    
    set in interface NdArray<Short>
    
    Parameters:
    
    src - an array of the values to assign
    
    coordinates - coordinates of the element to assign
    
    Returns:
    
    this array
  - getObject
```
default Short getObject(long... coordinates)
```
    Description copied from interface: NdArray
    Returns the value of the scalar found at the given coordinates.
    To access the scalar element, the number of coordinates provided must be equal to the number of dimensions of this array (i.e. its rank). For example:
```
  FloatNdArray matrix = NdArrays.ofFloats(shape(2, 2));  // matrix rank = 2
  matrix.getObject(0, 1);  // succeeds, returns 0.0f
  matrix.getObject(0);  // throws IllegalRankException

  FloatNdArray scalar = matrix.get(0, 1);  // scalar rank = 0
  scalar.getObject();  // succeeds, returns 0.0f
 
```
    Note: if this array stores values of a primitive type, prefer the usage of the specialized method in the subclass for that type. For example, floatArray.getFloat(0); .
    Specified by:
    
    getObject in interface NdArray<Short>
    
    Parameters:
    
    coordinates - coordinates of the scalar to resolve
    
    Returns:
    
    value of that scalar
  - setObject
```
default ShortNdArray setObject(Short value,
                               long... coordinates)
```
    Description copied from interface: NdArray
    Assigns the value of the scalar found at the given coordinates.
    To access the scalar element, the number of coordinates provided must be equal to the number of dimensions of this array (i.e. its rank). For example:
```
  FloatNdArray matrix = NdArrays.ofFloats(shape(2, 2));  // matrix rank = 2
  matrix.setObject(10.0f, 0, 1);  // succeeds
  matrix.setObject(10.0f, 0);  // throws IllegalRankException

  FloatNdArray scalar = matrix.get(0, 1);  // scalar rank = 0
  scalar.setObject(10.0f);  // succeeds
 
```
    Note: if this array stores values of a primitive type, prefer the usage of the specialized method in the subclass for that type. For example, floatArray.setFloat(10.0f, 0);
    Specified by:
    
    setObject in interface NdArray<Short>
    
    Parameters:
    
    value - the value to assign
    
    coordinates - coordinates of the scalar to assign
    
    Returns:
    
    this array
  - elements
```
NdArraySequence<ShortNdArray> elements(int dimensionIdx)
```
    Description copied from interface: NdArray
    Returns a sequence of all elements at a given dimension.
    Logically, the N-dimensional array can be flatten in a single vector, where the scalars of the (n - 1)th element precedes those of the (n)th element, for a total of NdArray.size() values.
    For example, given a n x m matrix on the [x, y] axes, elements are iterated in the following order:
    x₀y₀, x₀y₁, ..., x₀y_m-1, x₁y₀, x₁y₁, ..., x_n-1y_m-1
    The returned sequence can then be iterated to visit each elements, either by calling Iterable.forEach(Consumer) or NdArraySequence.forEachIndexed(BiConsumer).
```
    // Iterate matrix for initializing each of its vectors
    matrixOfFloats.elements(0).forEach(v -> {
      v.set(vector(1.0f, 2.0f, 3.0f));
    });

    // Iterate a vector for reading each of its scalar
    vectorOfFloats.scalars().forEachIdx((coords, s) -> {
      System.out.println("Value " + s.getFloat() + " found at " + coords);
    });
 
```
    Specified by:
    
    elements in interface NdArray<Short>
    
    Parameters:
    
    dimensionIdx - index of the dimension
