4 Using MWArra y Classes

Method Description

“newInstance” on

page 4-94

Constructs a logical array with the specified

dimensions.

“newSparse” on

page 4-95

Constructs a sparse logical matrix from the supplied

full matrix.

“dispose” on page

4-98

Frees the native MATLAB array contained by this

array.

“disposeArray” on

page 4-98

Frees all native M ATLAB arrays contained in the

input object.

newInstance. This method constructs a real or complex array, specifying the

array dimensions, type, and complexity. This is a static method of the class

and thus does no t need to be invoked in reference to an instance of the class.

Note This method offers better performance than using the class constructor.

To construct a logical array with specified dimensions and all elements

initialized to

false,usethefollowing:

public static MWLogicalArray newInstance(int[] dims)

To construct a logical array with specified dimensions and initialized to the

supplied data, use the following:

public static MWLogicalArray newInstance(int[] dims,

Object data)

Input Parameters

dims

Array of nonnegative dimension sizes

data

Data to initialize the array
