Method Detail

• ascending

  public DoubleMatrix3D ascending(int slices,
                                  int rows,
                                  int columns)

  Constructs a matrix with cells having ascending values. For debugging purposes.

• descending

  public DoubleMatrix3D descending(int slices,
                                   int rows,
                                   int columns)

  Constructs a matrix with cells having descending values. For debugging purposes.

• make

  public DoubleMatrix3D make(double[][][] values)

  Constructs a matrix with the given cell values. values is required to have the form values[slice][row][column] and have exactly the same number of slices, rows and columns as the receiver.

  The values are copied. So subsequent changes in values are not reflected in the matrix, and vice-versa.

  Parameters:

  values - the values to be filled into the cells.

  Returns:

  this (for convenience only).

  Throws:

  IllegalArgumentException - if values.length != slices() || for any 0 <= slice < slices(): values[slice].length != rows().

  IllegalArgumentException - if for any 0 <= column < columns(): values[slice][row].length != columns().

• make

  public DoubleMatrix3D make(int slices,
                             int rows,
                             int columns)

  Constructs a matrix with the given shape, each cell initialized with zero.

• make

  public DoubleMatrix3D make(int slices,
                             int rows,
                             int columns,
                             double initialValue)

  Constructs a matrix with the given shape, each cell initialized with the given value.

• random

  public DoubleMatrix3D random(int slices,
                               int rows,
                               int columns)

  Constructs a matrix with uniformly distributed values in (0,1) (exclusive).
