- MatrixFactory

```
public final class MatrixFactory
extends Object
```
Static utility methods for creating matrix. This factory selects one of the Matrix1, Matrix2, Matrix3, Matrix4 or GeneralMatrix implementation according the desired matrix size. Note that if the matrix size is know at compile time, it may be more efficient to invoke directly the constructor of the appropriate class instead.

- Method Detail
  - create
```
public static XMatrix create(int size)
```
    Creates a square identity matrix of size size × size.
    
    Parameters:
    
    size - For an affine transform, this is the number of source and target dimensions + 1.
    
    Returns:
    
    An identity matrix of the given size.
  - create
```
public static XMatrix create(int numRow,
                             int numCol)
```
    Creates a matrix of size numRow × numCol. Elements on the diagonal j==i are set to 1.
    
    Parameters:
    
    numRow - For an affine transform, this is the number of target dimensions + 1.
    
    numCol - For an affine transform, this is the number of source dimensions + 1.
    
    Returns:
    
    An identity matrix of the given size.
  - create
```
public static XMatrix create(Matrix matrix)
```
    Creates a new matrix which is a copy of the specified matrix.
