Matrix3x3 (Fiji Javadocs 0-SNAPSHOT API)

java.lang.Object
- mpicbg.util.Matrix3x3

All Implemented Interfaces:

Serializable
```
public final class Matrix3x3
extends Object
implements Serializable
```
Basic operations on 3x3 double matrices.
```
 m00 m01 m02
 m10 m11 m12
 m20 m21 m22
 
```
The class provides most of the methods as static variants for matrices passed as double[]. They are always meant to be in a row after row sequence:
```
 m00, m01, m02, m10, m11, m12, m20, m21, m22
 
```

public Matrix3x3(double[] m)
```
  Initialize a matrix with a double[]. Note that the double[] elements do not reflect the content of the matrix when performing operations. They are just used to initialize it. For performing operations on the double[] directly, use the static methods of Matrix3x3.
  
  Parameters:
