Using Class Methods

Method Description

“classID” on page 4-41 Returns the MATLAB type of the array.

“getDimensions” on page 4-42 Returns the size of each dimension of the

array.

“isEmpty” on page 4-42 Tests if the array has no elements.

“numberOfDimensions” on page

4-43

Returns the number of dimensions of the

array.

“numberOfElements” on page

4-43

Returns the total number of elements in

the array.

The e xamples in the fo ll owing secti ons use a 3-by-6 MWNumericArray object

A, as constructed by this Java code:

int[][] Adata = {{ 1, 2, 3, 4, 5, 6},

{ 7, 8, 9, 10, 11, 12},

{13, 14, 15, 16, 17, 18}};

MWNumericArray A = new MWNumericArray(Adata, MWClassID.INT32);

classID. This m ethod returns the MATLAB type of the MWArray object. The

return typ e is a field defined by the

MWClassID class.

The prototype for the

classID method is as fo llows:

public MWClassID classID()

Input Parameters

None

Example — Getting the Class I D of a n MWArray

Return the class ID for an MWNumericArray object created previously:

System.out.println("Class of A is " + A.classID());
