Class rn.operator.Matrix

java.lang.Object
   |
   +----rn.operator.Matrix

public class Matrix

extends Object

d

Matrix(float[][])

fast (second) index is the row dimension.

Matrix(int, int)

fast (second) index is the row dimension.
col -->
r | r11 r12 r13
o | r21 r22 r23
w V

The matrix has 3 columns and 2 rows.

Matrix(Matrix)

copy()

equals(Object)

Compares two Objects for equality.

getElement(int, int)

setElement(int, int, float)

toString()

Returns a string representation of the object.

 public float d[][]

 public Matrix(int row,
               int col)

fast (second) index is the row dimension.
col -->
r | r11 r12 r13
o | r21 r22 r23
w V

The matrix has 3 columns and 2 rows. The column index (0-2) is the fast, second index (the one you want to use inside of a for loop). Consequently, m.v[1][2] = r12 and vice versa.

 public Matrix(float v[][])

fast (second) index is the row dimension.

 public Matrix(Matrix src)

 public Matrix copy()

 public void setElement(int row,
                        int col,
                        float v)

 public float getElement(int row,
                         int col)

 public boolean equals(Object obj)

Compares two Objects for equality.

Overrides:

equals in class Object

 public String toString()

Returns a string representation of the object.

Overrides:

toString in class Object
