Guidelines for Working with MWArray Classes

Method Usage

sharedCopy()

Creates a new MWArray instance

that represents a shared copy of

the underlying MATLAB a rray.

A shared copy points to the same

underlying MATLAB array as the

original. Changing the data in a shared

copy also changes the original array.

toArray()

Returns an array containing a copy of

the data in the underlying M ATLAB

array as an array of Java types.

The returned array has the same

dimensionality as the underlying

MATLAB array. 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, a full

representation of the array is returned.

• If the underlying array is a cell or

struct array,

toArray is recursively

called on each element.

Constructing Numeric Arrays

The MWNumericArray classprovidesaJavainterfacetoanumericMATLAB

array. A n instance of this class can store a reference to a MATLAB array of

type

double, single, int8, uint8, int16, int32, uint32, int64,anduint64.

MWNumericArrays can be real or complex, dense or s parse (sparse is supported

for

double type only).
