Guidelines for Working with MWArray Classes

Method Usage

columnIndex()

Returns the column index (second

dimension) of each element in the array.

Call this method to get an a rray of

column indices for the nonzero elements

of a sparse array.

dispose()

Frees the native resources associated

with the underlying MATLAB array.

disposeArray(Object)

Calls dispose on all MWArray instances

contained in the input.

get(int)

Returns the elements at the specified

one-based offset.

get(int[])

Returns the elements at the specified

one-based index array.

getData()

Returns a one-dimensional array

containing a copy of the data in the

underlying MATLAB array as an array of

Java types. The elements in the returned

array are arranged in column-wise order.

The different kinds of arrays are returned

as follows:

• If the underlying MATLAB array is

complex, the real part is returned.

• If the underlying array is sparse, an

array containing the non zero elements

is returned.

• If the underlying array is a cell or

struct array,

toArray is recursively

called on each element.

getDimensions()

Returns an array of dimensions for the

array.

isEmpty()

Testsifthearrayisempty.

isSparse()

Tests if the array is sparse.
