以同步或异步方式从 Java 程序调用 MATLAB 函数和计算 MATLAB 语句。Java 程序可以将数据传递到 MATLAB 基础工作区,也可以从工作区获取数据。该引擎支持使用 JDK™ 7 或 8 编译的 Java 应用程序。
要从 MATLAB 调用 Java 函数,请参阅Java 库。
该 API 使 Java 程序能够将 MATLAB 用作计算引擎。
设置环境变量、Java 类路径,编译并运行您的 Java 代码。
These examples show how to use the MATLAB Engine API for Java.
Here is a summary of the classes and methods available to use the MATLAB Engine API for Java.
The MATLAB engine API provides mappings to pass Java data types to MATLAB and pass MATLAB data types to Java, including Java classes to accommodate MATLAB handle objects, cellstrs, structures, and complex arrays.
Start and Close MATLAB Session from Java
Start the Java engine session synchronously or asynchronously and you can pass startup options to MATLAB.
Connect Java to Running MATLAB Session
Connect the Java engine to a running MATLAB session that has been started as or converted to a shared session.
将 Java 变量传递给 MATLAB 函数调用,并将值返回给 Java。
Evaluate MATLAB Statements from Java
Evaluate MATLAB expressions from Java and write variables into the MATLAB base workspace.
Pass Variables from Java to MATLAB
Pass variables from Java to MATLAB as function arguments or by placing those variables in the MATLAB base workspace.
Pass Variables from MATLAB to Java
Get variables from the MATLAB workspace and map them to the appropriate Java type.
Redirect MATLAB Command Window Output to Java
Redirect standard output from the MATLAB command window to Java.
Using Complex Variables in Java
Define complex numbers in Java using the Complex
class.
Using MATLAB Structures in Java
Define MATLAB structure data types in Java using
the Struct
class.
Define a MATLAB cell array of character vectors
using the Java CellStr
class.
Using MATLAB Handle Objects in Java
Return MATLAB handle objects to Java using
the Java HandleObject
class.
Run Simulink Simulation from Java
You can run Simulink® simulations and return results to Java.
The MATLAB Engine API for Java defines specific exception classes for MATLAB.
Pass Java Array Arguments to MATLAB
MATLAB and Java display multidimensional arrays differently, but indexed references to array elements produce the same results.
Incorrect Number of Output Arguments
If you are calling a MATLAB function with no
or more than one output argument, you must provide that number in
calls to the engine feval
method.
In certain cases, you must convert to specific MATLAB types to support the requirements of the MATLAB function you are calling.
