Parameters:

i_1 - an index value.

Returns:

a key representing the index vector.

atKey

public java.lang.String atKey(int i_1,
                              int i_2)

Create a key for an 2 dimensional index reference. This key is used to store and retrieve values in the associate array.

Parameters:

i_1 - an index value.

i_2 - an index value.

Returns:

a key representing the index vector.

atKey

public java.lang.String atKey(int i_1,
                              int i_2,
                              int i_3)

Create a key for an 3 dimensional index reference. This key is used to store and retrieve values in the associate array.

Parameters:

i_1 - an index value.

i_2 - an index value.

i_3 - an index value.

Returns:

a key representing the index vector.

atKey

public java.lang.String atKey(int i_1,
                              int i_2,
                              int i_3,
                              int i_4)

Create a key for an 4 dimensional index reference. This key is used to store and retrieve values in the associate array.

Parameters:

i_1 - an index value.

i_2 - an index value.

i_3 - an index value.

i_4 - an index value.

Returns:

a key representing the index vector.

atKey

public java.lang.String atKey(int i_1,
                              int i_2,
                              int i_3,
                              int i_4,
                              int i_5)

Create a key for an 5 dimensional index reference. This key is used to store and retrieve values in the associate array.

Parameters:

i_1 - an index value.

i_2 - an index value.

i_3 - an index value.

i_4 - an index value.

i_5 - an index value.

Returns:

a key representing the index vector.

atKey

public java.lang.String atKey(int i_1,
                              int i_2,
                              int i_3,
                              int i_4,

Create a key for an 6 dimensional index reference. This key is used to store and retrieve values in the associate array.

Parameters:

i_1 - an index value.

i_2 - an index value.

i_3 - an index value.

i_4 - an index value.

i_5 - an index value.

i_6 - an index value.

Returns:

a key representing the index vector.

retrieve

public double retrieve(java.lang.String aKey)

Retrieve a value from the associate array using the supplied key.

Parameters:

aKey - the key.

Returns:

the stored value.

store

public void store(double aValue,
                  java.lang.String aKey)

Store a data value at a particular location given by the key string.

Parameters:

aValue - the value.

aKey - the key.

readMatrix

public void readMatrix(java.lang.String filename)

Read in a matrix with a given name and store it into a associative data structure. The associate data structure make the access of the data simple. Instead of reading from a file system, the method reads from the source matrix supplied by SourceMatrix class. This make the access of the matrix possible inside a Applet.

Parameters:

filename - The filename.

writeMatrix

public void writeMatrix(java.lang.String filename)

Write the matrix stored in the associate array with a given name. Currently not further implemented.

Parameters:

filename - the filename.
