4 Using MWArra y Classes

Example — Getting a Boolean Value from a Logical Array

boolean[][] Adata = {{true, false, false},

{false, true, false}};

MWLogicalArray A = new MWLogicalArray(Adata);

int[] index = {2, 2};

System.out.println("A(2,2) is " + A.getBoolean(index));

When run, the example displays this output:

A(2,2) = true

set. This m ethod returns the element located at the spe cifie d one-based index

of the

MWLogicalArray object.

To set the element at a specific index, use one of the following:

public void set(int index, boolean element)

public void set(int[] index, boolean element)

Use the first syntax (int index) to return the ele ment at the specified

one-based offset in the a rray, accessing elements in column-wise order. Us e the

second syntax (

int[] index) to return the element at the specified array of

one-based indices. The first syntax offers better performance than the second.

Input Parameters

element

New element to replace at index

index

Index of the requested element in the MWLogicalArray

In the case where index is of type int, the valid range for index is 1<=index

<= N

,whereN is the total number of elements in the array.
