Interface MatrixData

All Superinterfaces:

DeepCopyable

All Known Implementing Classes:

DenseData

public interface MatrixData
extends DeepCopyable

This interface defines for (an abstract) storage of matrix data.

It allow us to:

1. We can provide default implementations for some matrix operations that do not depend on the particular matrix implementation. E.g., MatrixMathImpl. 2. Conceivably, we could experiment different ways of implementing a matrix. This interface allows us to swap implementations.

Method Summary

double	get(int row, int col) Get the matrix entry at [row, col].
void	set(int row, int col, double value) Set the matrix entry at [row, col] to value.

Method Detail

set

void set(int row,
         int col,
         double value)

Set the matrix entry at [row, col] to value.

This is the only function that may change the entries of a matrix.

Parameters:

row - the row index

col - the column index

value - the value to set A[row, col] to

Throws:

MatrixAccessException - if row or col is out of range

get

double get(int row,
           int col)

Get the matrix entry at [row, col].

Parameters:

row - the row index

col - the column index

Returns:

A[row, col]

Throws:

MatrixAccessException - if row or col is out of range
