DenseDoubleMatrix1D (baseCode 1.1.21-SNAPSHOT API)

java.lang.Object
- cern.colt.PersistentObject
- - cern.colt.matrix.impl.AbstractMatrix

        ubic.basecode.dataStructure.matrix.DenseDoubleMatrix1D

All Implemented Interfaces:

Serializable, Cloneable
```
public class DenseDoubleMatrix1D
extends cern.colt.matrix.impl.DenseDoubleMatrix1D
```
Use this class when fast iteration over the matrix is of primary interest. The primary change is that getQuick is faster, and toArray returns the actual elements, not a copy.

- Method Detail
  - getQuick
```
public double getQuick(int i)
```
    This is an optimized version of getQuick. Implementation note: the superclass uses an add and a multiply. This is faster, but there might be unforseen consequences...
    
    Overrides:
    
    getQuick in class cern.colt.matrix.impl.DenseDoubleMatrix1D
    
    See Also:
    
    DoubleMatrix1D.getQuick(int)
  - toArray
```
public double[] toArray()
```
    WARNING unlike the superclass, this returns the actual underlying array, not a copy.
    
    Overrides:
    
    toArray in class cern.colt.matrix.DoubleMatrix1D
    
    Returns:
    
    the elements
