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 FloatBigVector.

Returns:

factory

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
