4 Using MWArra y Classes

Example—GettinganMWArrayValuewithget

Retrieve element (2, 4) from array object A:

int[] index = {2, 4};

Object d_out = A.get(index);

System.out.println("Data read from A(2,4) is " +

d_out.toString());

When run, the example displays this output:

Data read from A(2,4) is 10

getData. This method returns a ll elements of the MWArray object. Elements

are returned in a one-dimensional array, in column-wise order. Elements

are returned as type

Object.

The prototype for the

getData method is as fo llows:

public Object getData()

Input Parameters

None

The elements of the returned array are converted according to default

conversion rules. If the underlying MATLAB array is a complex numeric

type,

getData returns the real part.

Example — Ge tting an MWArray Value with getData

Get the data from MWArray object A , casting the type from Object to int:

System.out.println("Data read from matrix A is:");

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

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

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