```
public DynamicDoubleArray(int initialCapacity)
```
    Dynamic array of integers with provided initial capacity
    
    Parameters:
    
    initialCapacity - initial capacity. If <= 0, uses the default capacity

  - remove
```
public void remove(int idx,
                   int count)
```
    Remove a specified number of elements starting at the provided index.
    
    Parameters:
    
    idx - starting index to remove
    
    count - number of elements to remove
  - trimToSize
```
public void trimToSize()
```
  - resize
```
public void resize(int size)
```
    Resizes the array. If the new size is smaller than the current array size, then the trailing elements are removed from the array. If the new size is greater than the current, then the array is grown, and new elements are initialized to zero.
    
    Parameters:
    
    size - new size
  - slice
```
public DynamicDoubleArray slice(int start,
                                int size)
```
    Returns a copy of a portion of the array
    
    Parameters:
    
    start - starting index to copy
    
    size - number of elements
    
    Returns:
    
    portion of array
  - chop
```
public void chop(int start,
                 int size)
```
    Performs an in-place slice, modifying this array directly
    
    Parameters:
    
    start - starting index to keep
    
    size - number of elements
  - get
```
public double get(int idx)
```
  - set
```
public void set(int idx,
                double e)
```
    Sets the value at index idx to the provided e. If idx==size(), then the element is appended to the array.
    
    Parameters:
    
    idx - index at which to modify the value
    
    e - new value
  - getArray
```
public double[] getArray()
```
    Provides direct access to the underlying array. If the array is modified, then the version numbering will be out of sync until ModifiedVersionBase.notifyModified() is called. The underying array is automatically trimmed to the correct size before being returned.
    
    Returns:
    
    the underlying array.
  - toArray
```
public double[] toArray()
```
    Copies the contents of this DynamicDoubleArray into an array.
    
    Returns:
    
    new array
  - clone
```
public DynamicDoubleArray clone()
```
    Creates a shallow copy
    
    Overrides:
    
    clone in class java.lang.Object
  - equals
```
public boolean equals(DynamicDoubleArray array)
```
    Returns true if this DynamicDoubleArray is equals to another one.
    
    Parameters:
    
    array - array to compare with
