Using Class Methods

System.out.println("The real data in matrix A is:");

x = (double[]) A.getData();

for (int i = 0; i < x.length; i++)

System.out.print(" " + x[i]);

System.out.println();

System.out.println("The imaginary data in matrix A is:");

x = (double[]) A.getImagData();

for (int i = 0; i < x.length; i++)

System.out.print(" " + x[i]);

System.out.println();

When run, the example displays this output:

The real data in matrix A is:

2.0 8.0 14.0 3.0 9.0 15.0 4.0 10.0 16.0

The imaginary data in matrix A is:

6.0 7.0 1.0 5.0 1.0 1.0 14.0 23.0 9.0

getImagDouble. This method returns the imaginary part of the

MWNumericArray element located at the specified one-based index or index

array. The return value is given type

double.

Use either of the following prototypes f or the

getImagDouble method, where

index can be of type int or int[]:

public double getImagDouble(int index)

public double getImagDouble(int[] index)

Example — Getting Complex Data of a Specific Type

Using the same array as in the example for “getImag” on page 4 -81, get the

real and imaginary parts of one element of the

MWNumericArray:

int[] index = {2, 3};

System.out.println("The real part of A(2,3) = " +

A.getDouble(index));
