  - get
```
public double get(int row,
                  int col)
```
    Description copied from interface: RealMatrix64F
    
    Returns the value of value of the specified matrix element.
    
    Specified by:
    
    get in interface RealMatrix64F
    
    Parameters:
    
    row - Matrix element's row index..
    
    col - Matrix element's column index.
    
    Returns:
    
    The specified element's value.
  - unsafe_get
```
public double unsafe_get(int row,
                         int col)
```
    Description copied from interface: RealMatrix64F
    
    Same as RealMatrix64F.get(int, int) but does not perform bounds check on input parameters. This results in about a 25% speed increase but potentially sacrifices stability and makes it more difficult to track down simple errors. It is not recommended that this function be used, except in highly optimized code where the bounds are implicitly being checked.
    
    Specified by:
    
    unsafe_get in interface RealMatrix64F
    
    Parameters:
    
    row - Matrix element's row index..
    
    col - Matrix element's column index.
    
    Returns:
    
    The specified element's value.
  - set
```
public void set(int row,
                int col,
                double val)
```
    Description copied from interface: RealMatrix64F
    
    Sets the value of the specified matrix element.
    
    Specified by:
    
    set in interface RealMatrix64F
    
    Parameters:
    
    row - Matrix element's row index..
    
    col - Matrix element's column index.
    
    val - The element's new value.
  - unsafe_set
```
public void unsafe_set(int row,
                       int col,
                       double val)
```
    Description copied from interface: RealMatrix64F
    
    Same as RealMatrix64F.set(int, int, double) but does not perform bounds check on input parameters. This results in about a 25% speed increase but potentially sacrifices stability and makes it more difficult to track down simple errors. It is not recommended that this function be used, except in highly optimized code where the bounds are implicitly being checked.
    
    Specified by:
    
    unsafe_set in interface RealMatrix64F
    
    Parameters:
    
    row - Matrix element's row index..
    
    col - Matrix element's column index.
    
    val - The element's new value.
  - set
```
public void set(Matrix original)
```
    Description copied from interface: Matrix
    
    Sets this matrix to be identical to the 'original' matrix passed in.
    
    Specified by:
    
    set in interface Matrix
  - getNumRows
```
public int getNumRows()
```
    Description copied from interface: Matrix
    
    Returns the number of rows in this matrix.
    
    Specified by:
    
    getNumRows in interface Matrix
    
    Returns:
    
    Number of rows.
  - getNumCols
```
public int getNumCols()
```
    Description copied from interface: Matrix
    
    Returns the number of columns in this matrix.
    
    Specified by:
    
    getNumCols in interface Matrix
    
    Returns:
    
    Number of columns.
  - getNumElements
```
public int getNumElements()
```
    Description copied from interface: RealMatrix64F
    
    Returns the number of elements in this matrix, which is the number of rows times the number of columns.
    
    Specified by:
    
    getNumElements in interface RealMatrix64F
    
    Returns:
    
    Number of elements in this matrix.
  - copy
```
public <T extends Matrix> T copy()
```
    Description copied from interface: Matrix
    
    Creates an exact copy of the matrix
    
    Specified by:

```
public void print()
```
    Description copied from interface: Matrix
    
    Prints the matrix to standard out.
    
    Specified by:
