public RQ(int m,
          int n)
```
    Constructs an empty RQ decomposition
    
    Parameters:
    
    m - Number of rows
    
    n - Number of columns. Must be larger than or equal the number of rows

```
public static RQ factorize(Matrix A)
```
    Convenience method to compute an RQ decomposition
    
    Parameters:
    
    A - Matrix to decompose. Not modified
    
    Returns:
    
    Newly allocated decomposition
  - factor
```
public RQ factor(DenseMatrix A)
```
    Computes an orthogonal decomposition
    
    Parameters:
