Constructor Detail

DynamicMatrixOfVectors

public DynamicMatrixOfVectors()

Initialises the matrix (with size=1) and sets the dimension, which cannot be changed afterwards

Method Detail

main

public static void main(java.lang.String[] args)

get

public Vector get(int position)

Get the vector from the specified position. When the position lies outside the actual physical size of the data array, a value of null is returned (optionally it could return a vector of zeros, but it could trigger errors as it wouldn't correspond to actual data.

Specified by:

get in class DynamicMatrix

Parameters:

position -

Returns:

vector at the given position

add

public int add(Vector vector)

Adds a new vector to the matrix, in the last available slot

Parameters:

vector -

put

public int put(Vector vector,
      int position)

Store the vector in the specified position of the array. The array will increase in size to include this position, if necessary.

Parameters:

position -

vector -

length

public int length()

getMatrix

public Vector[] getMatrix()

Specified by:

getMatrix in class DynamicMatrix

Returns:

a copy of the entire matrix

display

public void display()
