Finds the decomposition of a matrix in the form of:

A = O*T*O^T

where A is a symmetric m by m matrix, O is an orthogonal matrix, and T is a tridiagonal matrix.

- Method Detail
  - getT
```
MatrixType getT(MatrixType T)
```
    Extracts the tridiagonal matrix found in the decomposition.
    
    Parameters:
    
    T - If not null then the results will be stored here. Otherwise a new matrix will be created.
    
    Returns:
    
    The extracted T matrix.
  - getQ
```
MatrixType getQ(MatrixType Q,
                boolean transposed)
```
    An orthogonal matrix that has the following property: T = Q^HAQ
    
    Parameters:
    
    Q - If not null then the results will be stored here. Otherwise a new matrix will be created.
    
    transposed - If true then the transpose (real) or conjugate transpose (complex) of Q is returned.
    
    Returns:
    
    The extracted Q matrix.
