ASingleBandMatrix

public ASingleBandMatrix()

Method Detail

nonZeroBand

public abstract int nonZeroBand()

Override to specify which band of the matrix is nonzero

Returns:

getNonZeroBand

public abstract AVector getNonZeroBand()

Override to specify which band of the matrix is nonzero

Returns:

isSymmetric

public boolean isSymmetric()

Description copied from class: AMatrix

Returns true if a matrix is symmetric

Overrides:

isSymmetric in class ABandedMatrix

isZero

public boolean isZero()

Description copied from class: AMatrix

Returns true if the matrix is the zero matrix (all components zero)

Specified by:

isZero in interface INDArray

Overrides:

isZero in class AMatrix

Returns:

nonZeroCount

public long nonZeroCount()

Description copied from interface: INDArray

Returns the number of non-zero elements in the array.

Specified by:

nonZeroCount in interface INDArray

Overrides:

nonZeroCount in class ABandedMatrix

Returns:

getBand

public AVector getBand(int band)

Description copied from class: AMatrix

Gets a specific band of the matrix, as a view vector. The band is truncated at the edges of the matrix, i.e. it does not wrap around the matrix.

Specified by:

getBand in class ABandedMatrix

Returns:
