Class DenseDoubleMatrix1D

java.lang.Object

cern.colt.PersistentObject

cern.colt.matrix.impl.AbstractMatrix

cern.colt.matrix.impl.AbstractMatrix1D

cern.colt.matrix.DoubleMatrix1D

cern.colt.matrix.impl.DenseDoubleMatrix1D

ubic.basecode.dataStructure.matrix.DenseDoubleMatrix1D

All Implemented Interfaces:

Serializable, Cloneable

public class DenseDoubleMatrix1D
extends 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 Details

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 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 DoubleMatrix1D

Returns:

the elements
