4 Using MWArra y Classes

Calling Sy n ta x. To get the element at a specific index, use one of the

following:

public type getType(int index)

public

type getType(int[] index)

To set the element at a specific index, use one of the following:

public void set(int index, type element)

public void set(int[] index,

type element)

Use the first syntax (int index) to return the ele ment at the specified

one-based offset in the a rray, accessing elements in column-wise order. Us e the

second syntax (

int[] index) to return the element at the specified array of

one-based indices. The first syntax offers better performance than the second.

In the case where

index is of type int, the valid range for index is 1<=index

<= N

,whereN is the total number of elements in the array.

Inthecasewhere

index is of type int[],eachelementoftheindex vector

is an index along one dimension of the

MWNumericArray object. The valid

range for any index is

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

ith dimension.

Exceptions. The

MWNumericArray constructor throws the following exception:

IndexOutOfBoundsException

The specified index parameter is invalid.

get.

MWNumericArray inherits this method from the MWArray class.

getData.

MWNumericArray inherits this method from the MWArray class.

getDouble. This method returns the real part of the

MWNumericArray

element located at the specified one-based index or index array. The return

value is given type

double.
