Using Class Methods

Exceptions

The newInstance method throws the following exceptions:

NegativeArraySizeException

The specified dims para m eter is negative.

ArrayStoreException

The specified data is nonnumeric or non-Boolean.

Example — Constructing a Logical Array Object w ith newInstance

Construct a 1-by-5 logical array using the newInstance method. Note that

data in the Java array must be stored in a column-wise order so that it will be

in row-wise order in the final

MWLogicalArray object.

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

int[] dims = {1, 5};

MWLogicalArray A = MWLogicalArray.newInstance(dims, Adata);

System.out.println("Array A: " + A.toString());

When run, the example displays this output:

Array A: 1 1 0 0 1

newSparse. This method constructs a sparse MWLogicalArray with the

specified number of rows and columns and m aximum nonzero elements, and

initializes the array with the supplied data. This is a static method of the class

and thus does no t need to be invoked in reference to an instance of the class.

Supported Prototypes

Supported prototypes for newSparse are as follows. All input parameters

shown here are described under Input Parameters on page 96. Any

parameters not specified are given their default values.
