Using Class Methods

Inthecasewhereindex is of type int[],eachelementoftheindex vector

is an index along one dimension of the

MWLogicalArray object. The valid

range for any index is

1 <= index[i] <= N[i],whereN[i] is the size of the

ith dimension.

Exceptions

The set method throws the following exception:

IndexOutOfBoundsException

The specified index parameter is invalid.

Example—SettingaValueinaLogicalArray

Get and modify the value at A(2,3):

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

{false, true, false}};

MWLogicalArray A = new MWLogicalArray(Adata);

int[] index = {2, 3};

Object d_out = A.get(index);

System.out.println("Array element A(2,3) is " +

d_out.toString() + "\n");

System.out.println("Setting A(2,3) to true\n");

A.set(index, true);

d_out = A.get(index);

System.out.println("Array element A(2,3) is " +

d_out.toString() + "\n");

When run, the example displays this output:

Array element A(2,3) is false
