## cern.colt.matrix
Class ObjectFactory1D

    java.lang.Object
      cern.colt.PersistentObject
          cern.colt.matrix.ObjectFactory1D

All Implemented Interfaces:
  Cloneable, Serializable

public class ObjectFactory1D
extends PersistentObject

Factory for convenient construction of 1-d matrices holding `Object` cells. Use idioms like `ObjectFactory1D.dense.make(1000)` to construct dense matrices, `ObjectFactory1D.sparse.make(1000)` to construct sparse matrices. If the factory is used frequently it might be useful to streamline the notation. For example by aliasing:

    ObjectFactory1D F = ObjectFactory1D.dense;
    F.make(1000);
    ...

Field Detail

### dense

    public static final ObjectFactory1D dense

  A factory producing dense matrices.

### sparse

    public static final ObjectFactory1D sparse

  A factory producing sparse matrices.

Method Detail

### append

    public ObjectMatrix1D append(ObjectMatrix1D A,
                                 ObjectMatrix1D B)

  C = A||B; Constructs a new matrix which is the concatenation of two other matrices. Example: `0 1` append `3 4` --> `0 1 3 4`.

### make

    public ObjectMatrix1D make(ObjectMatrix1D[] parts)

  Constructs a matrix which is the concatenation of all given parts. Cells are copied.

### make

    public ObjectMatrix1D make(Object[] values)

  Constructs a matrix with the given cell values. 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 new matrix.

### make

    public ObjectMatrix1D make(int size)

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

### make

    public ObjectMatrix1D make(int size,
                               Object initialValue)

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

### make

    public ObjectMatrix1D make(ObjectArrayList values)

  Constructs a matrix from the values of the given list. 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 new matrix.
  Returns:
    a new matrix.

### repeat

    public ObjectMatrix1D repeat(ObjectMatrix1D A,
                                 int repeat)

  C = A||A||..||A; Constructs a new matrix which is concatenated `repeat` times. Example:

      0 1
      repeat(3) -->
      0 1 0 1 0 1

### toList

    public ObjectArrayList toList(ObjectMatrix1D values)

  Constructs a list from the given matrix. The values are copied. So subsequent changes in `values` are not reflected in the list, and vice-versa.

  Parameters:
    `values` - The values to be filled into the new list.
  Returns:
    a new list.
