(Of course, result lists indexes are guaranteed to correspond to the same cell).

    Construct and returns a new 2-d matrix of the corresponding dynamic type, entirelly independent of the receiver. For example, if the receiver is an instance of type DenseFloatMatrix1D the new matrix must be of type DenseFloatMatrix2D, if the receiver is an instance of type SparseFloatMatrix1D the new matrix must be of type SparseFloatMatrix2D, etc.

    columns - the number of columns the matrix shall have.
    
    Returns:
    
    a new matrix of the corresponding dynamic type.

  - setQuick
```
public void setQuick(int index,
                     float value)
```
    Description copied from class: FloatMatrix1D
    
    Sets the matrix cell at coordinate index to the specified value.
    Provided with invalid parameters this method may access illegal indexes without throwing any exception. You should only use this method when you are absolutely sure that the coordinate is within bounds. Precondition (unchecked): index<0 || index>=size().
    
    Specified by:
    
    setQuick in class FloatMatrix1D
    
    Parameters:
    
    index - the index of the cell.
    
    value - the value to be filled into the specified cell.
  - swap
```
public void swap(FloatMatrix1D other)
```
    Description copied from class: FloatMatrix1D
    
    Swaps each element this[i] with other[i].
    
    Overrides:
    
    swap in class FloatMatrix1D
  - toArray
```
public void toArray(float[] values)
```
    Description copied from class: FloatMatrix1D
    
    Fills the cell values into the specified 1-dimensional array. The values are copied. So subsequent changes in values are not reflected in the matrix, and vice-versa. After this call returns the array values has the form
    for (int i=0; i < size(); i++) values[i] = get(i);
    
    Overrides:
    
    toArray in class FloatMatrix1D
  - zDotProduct
```
public float zDotProduct(FloatMatrix1D y,
                         int from,
                         int length)
```
    Description copied from class: FloatMatrix1D
    
    Returns the dot product of two vectors x and y, which is Sum(x[i]*y[i]). Where x == this. Operates on cells at indexes from .. Min(size(),y.size(),from+length)-1.
    
    Overrides:
    
    zDotProduct in class FloatMatrix1D
    
    Parameters:
    
    y - the second vector.
    
    from - the first index to be considered.
    
    length - the number of cells to be considered.
    
    Returns:
    
    the sum of products; zero if from<0 || length<0.
  - zSum
```
public float zSum()
```
    Description copied from class: FloatMatrix1D
    
    Returns the sum of all cells; Sum( x[i] ).
    
    Overrides:
    
    zSum in class FloatMatrix1D
    
    Returns:
    
    the sum.
  - index
```
public long index(int rank)
```
    Description copied from class: AbstractMatrix1D
    
    Returns the position of the element with the given relative rank within the (virtual or non-virtual) internal 1-dimensional array. You may want to override this method for performance.
    
    Overrides:
    
    index in class AbstractMatrix1D
    
    Parameters:
    
    rank - the rank of the element.
