Method Details

count

public long count()

Description copied from interface: Structure1D

The total number of elements in this structure.

You only need to implement this method if the structure can contain more than Integer.MAX_VALUE elements.

Specified by:

count in interface Structure1D

Overrides:

count in class Access2D.ColumnView<N extends Comparable<N>>

doubleValue

public double doubleValue(int index)

Specified by:

doubleValue in interface Access1D<N extends Comparable<N>>

Overrides:

doubleValue in class Access2D.ColumnView<N extends Comparable<N>>

first

public int first()

Description copied from interface: Householder

Regardless of what is actually returned by Access1D.doubleValue(long) and/or Access1D.get(long) vector elements with indeces less than 'first' should be assumed to be, and treated as if they are, zero.

Specified by:

first in interface Householder<N extends Comparable<N>>

get

public N get(long index)

Specified by:

get in interface Access1D<N extends Comparable<N>>

Overrides:

get in class Access2D.ColumnView<N extends Comparable<N>>

getWorker

public <P extends Householder<N>> P getWorker(PhysicalStore.Factory<N,?> factory)

Specified by:

getWorker in interface HouseholderReference<N extends Comparable<N>>

isZero

public boolean isZero()

Specified by:

isZero in interface HouseholderReference<N extends Comparable<N>>

point

public void point(long row,
 long col)

Specified by:

point in interface HouseholderReference<N extends Comparable<N>>
