Method Detail

setDefaultVectorClass

public static void setDefaultVectorClass(Class<?> vectorClass)

getDefaultVectorClass

public static Class<?> getDefaultVectorClass()

setSemanticMapper

public static void setSemanticMapper(SemanticMapper semanticMapper)

getSemanticMapper

public static SemanticMapper getSemanticMapper()

getInstance

public static MatrixFactory getInstance(Class<?> vectorClass)

Retourne une factory utilisant vectorClass comme classe de base a l'implantation des matrices.

Parameters:

vectorClass - vector class implementation

Returns:

factory

getInstance

public static MatrixFactory getInstance()

Utilise par defaut defaultVectorClass. Si une factory a ete initialisee pour le thread local, alors celle-ci sera reutilise, sinon une nouvelle est cree avec le backend par defaut

Returns:

factory

initMatrixFactoryThreadLocal

public static void initMatrixFactoryThreadLocal(Class<?> vectorClass)

Initialise une factory pour le thread courant avec le vectorClass passe en parametre.

Parameters:

vectorClass -

removeMatrixFactoryThreadLocal

public static void removeMatrixFactoryThreadLocal()

Retire la factory pour le thread courant

create

public MatrixND create(int[] dim)

create

public MatrixND create(double[] values,
              int[] dim)

Convert a double array into matrix.

Parameters:

values - The values to fill the matrix

dim - An array representing the dimensions of the matrix

Returns:

a 2D matrix filled with the values, null if the dimension is more than 2

create

public MatrixND create(List<?>[] semantics)

create
