                   Object value)
```
    Description copied from interface: MatrixValueI
    
    sets the i-th element, treats data a a linear array.
    
    Specified by:
    
    setEle in interface MatrixValueI
  - setEle
```
public void setEle(int i,
                   int j,
                   Object value)
```
  - getEle
```
public Object getEle(int n)
```
    Description copied from interface: MatrixValueI
    
    gets the i-th element, treats data a a linear array.
    
    Specified by:
    
    getEle in interface MatrixValueI
  - getEle
```
public Object getEle(int i,
                     int j)
```
  - getEles
```
public Object[][] getEles()
```
  - setEles
```
public void setEles(MatrixValueI val)
```
    sets the elements to those of the arguments.
    
    Specified by:
    
    setEles in interface MatrixValueI
  - equals
```
public boolean equals(Object obj)
```
    Are two matrices equal, element by element Overrides Object.
    
    Overrides:
    
    equals in class Object
  - hashCode
```
public int hashCode()
```
    Always override hashCode when you override equals. Effective Java, Joshua Bloch, Sun Press
    
    Overrides:
    
    hashCode in class Object
