What Is MATLAB Builder for Java?

MATLAB Builder for Java (also called Java Builder) is an extension to

MATLAB Compiler. Use Java Builder to w rap MATLAB functions into one

or more Java classes that make up a Java compon ent, or package. Each

MATLAB function is encapsulated as a method of a Java class and can be

invoked from w ithin a Java application.

When you package and distribute the a pplication to your users, you must

include supporting files generated by Java Builder as well as the MATLAB

Component Runtime (MCR), which is provided by the product. Your users do

not have to purchase and install MATLAB.

Note MATLAB Builder for Java is also referred to in this documentation as

Java Builder, for ease of use.

Support for MATLAB Features in Java

Java Builder provides robust data conversion, indexing, and array formatting

capabili ties to preserve the flexi bility of MATLAB when called from Java

code. To support the MATLAB data types, Jav a Builder provides the

MWArray

class hierarchy. You can use MWArray and other Java class members in your

application to convert native arrays to MATLAB arrays and vice versa. Java

Builder also provides automatic data conversion for passing arguments that

are Java types.

Known Issue in Data Returned by toArray

Referencing S parse Format

There is a known issue where the data returned by calling toArray on a

MWNumericArray or MWLogicalArray object that references a M ATLAB array

stored in sparse format may be incorrect or corrupted. If this use case applies

to your work, see “Version 1.0 (R2006b) MATLAB Builder for Java” in the

Release Notes for a link to information and a patch to fix this problem.
