SquareMatrixSupport.RealSquareMatrix

All Known Implementing Classes:

SquareMatrixSupport.ArrayRealSquareMatrix

Enclosing class:

SquareMatrixSupport
```
static interface SquareMatrixSupport.RealSquareMatrix
```
Define a real-valued square matrix.
This matrix supports a scale to protect against overflow. The true value of any matrix value is multiplied by 2^scale. This is readily performed using Math.scalb(double, int).

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`int`	`dimension()`	Gets the dimension for the rows and columns.
`double`	`get(int i, int j)`	Gets the value.
`SquareMatrixSupport.RealSquareMatrix`	`power(int n)`	Returns the result of multiplying `this` with itself `n` times.

- Method Detail
  - dimension
```
int dimension()
```
    Gets the dimension for the rows and columns.
    
    Returns:
    
    the dimension
  - scale
```
int scale()
```
    Gets the scale of the matrix values. The true value is the value returned from get(int, int) multiplied by 2^scale.
    
    Returns:
    
    the scale
  - get
```
double get(int i,
           int j)
```
    Gets the value. This is a scaled value. The true value is the value returned multiplied by 2^scale.
    
    Parameters:
    
    i - Row
    
    j - Column
    
    Returns:
    
    the value

    scale()
  - power
```
SquareMatrixSupport.RealSquareMatrix power(int n)
```
    Returns the result of multiplying this with itself n times.
    
    Parameters:
    
    n - raise this to power n
    
    Returns:
    
    this^n
    
    Throws:
    
    java.lang.IllegalArgumentException - if n < 0
