4 Using MWArra y Classes

classID. MWNumericArray inherits this method from the MWArray class.

complexity. This method returns the complexity of the

MWNumericArray

object as either MWComplexity.REAL for a real array, or MWComplexity.COMPLEX

for a complex array.

The prototype for the

complexity method is

public MWComplexity complexity()

Input Parameters

None

Example — Testing for a Complex Array

Determine whether matrix A is real or complex:

double AReal = 24;

double AImag = 5;

MWNumericArray A = new MWNumericArray(AReal, AImag);

System.out.println("A is a " + A.complexity() + " matrix");

When run, the example displays this output:

A is a complex matrix

getDimensions. MWNumericArray inherits this m ethod from the MWArray

class.

isEmpty.

MWNumericArray inherits this method from the MWArray class.

isFinite. This method tests for finiteness in a machine-independent manner.

This is a static m ethod of the class and does not need to be invoked in

reference to an i nstance of the class.

The prototype for the

isFinite method is as follows:

public static boolean isFinite(double value)
