Constructor Detail

SVDResult

public SVDResult(AMatrix U,
                 AMatrix S,
                 AMatrix V,
                 AVector singularValues)

Method Detail

getU

public AMatrix getU()

Returns the orthogonal 'U' matrix.

Specified by:

getU in interface ISVDResult

Returns:

An orthogonal matrix.

getS

public AMatrix getS()

Returns a diagonal matrix with the singular values. Order of the singular values is not guaranteed.

Specified by:

getS in interface ISVDResult

Returns:

matrix with singular values along the diagonal.

getV

public AMatrix getV()

Returns the orthogonal 'V' matrix.

Specified by:

getV in interface ISVDResult

Returns:

An orthogonal matrix.

getSingularValues

public AVector getSingularValues()

Description copied from interface: ISVDResult

Returns an array containing singular values. The non zero singular values are the square roots of the non-zero eigenvalues of M^TM and MM^T, where M is the input matrix.

Specified by:

getSingularValues in interface ISVDResult

Returns:
