Using Class Methods

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.

Input Parameters

index

Index of the requested element in the MWCellArray

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

MWCellArray object. The valid range

for any index is

1 <= index[i] <= N[i],whereN[i] isthesizeoftheith

dimension.

Exceptions

The get method throws the following exception:

IndexOutOfBoundsException

The specified index parameter is invalid.

Example — Getting Data from a Cell Array with get

Use get to read index (1,3) of MWCellArray object C:

int[] cdims = {1, 3};

MWCellArray C = new MWCellArray(cdims);

Integer val = new Integer(15);

int[] index = {1, 3};
