mcc

java调用matlab需要，mcc编译器的参与，mcc命令参数如下

mcc Compile MATLAB functions for deployment outside MATLAB.
mcc [-options] fun [fun2…]

mcc Compile MATLAB functions for deployment outside MATLAB.
Options applicable across all deployment targets:
-? Display help for the mcc command
-a Add additional files or directories to be included in the build
-d Build output directory
-g Include debugging symbol information
-I Add a directory to be searched for MATLAB files
-v Verbose display of build

MATLAB Compiler
Standalone Application (MATLAB|Hadoop|Spark)
mcc -m <matlabFile.m>

Excel Add-In
mcc -W ‘excel:,’ -T link:lib -b <matlabFile.m>

Hadoop Deployable Archive
mcc -H -W ‘hadoop:,CONFIG:<configFile.txt>’ <mapperFile.m> <reducerFile.m> <datastoreInfo.mat>

Spark Application
mcc -C -W ‘spark:,’ <matlabFile.m>

MATLAB Compiler SDK
C Shared Library
mcc -W lib: -T link:lib <matlabFile.m>

C++ Shared Library
mcc -W cpplib: -T link:lib <matlabFile.m>

.NET Assembly
mcc -W ‘dotnet:,’ -T link:lib <matlabFile.m>

Java Package
mcc -W ‘java:,’ -T link:lib <matlabFile.m>

Python Package
mcc -W python: -T link:lib <matlabFile.m>

COM Component
mcc -W ‘com:’ -T link:lib <matlabFile.m>

MATLAB Production Server
Deployable Archive
mcc -W CTF: -U <matlabFile.m>

Deployable Archive for Excel Add-In
mcc -W mpsxl: -T link:lib <matlabFile.m>

Replace any single quotes (’ ') in the above syntax with double quotes (" ") when executing the mcc command from a Windows Command Prompt.

For more details, execute “doc mcc” from MATLAB.

mcc可以把m文件打包exe或者dll，也可以把m文件（包含m文件调用cpp文件）打包成exe
打包的m文件函数，可以直接传参数运行，类似main函数

matlab的例子

matlab函数文件，sumd.m

function sd =sumd(a,b,c)
sd=a+b+c;
end

通过matlab命令行编译

mcc -W ‘java:sumd,sumd’ -T link:lib sumd.m

输出一下文件

java调用matlab

package htck;

import java.io.UnsupportedEncodingException;
import sumd.sumd;

public class sumd_test {
    public static void main(String[] args) throws UnsupportedEncodingException {
        try {
            sumd obj = new sumd();
            Object[] result = obj.sumd(1,1, 2,3);
            System.out.println(result[0]);

            obj.sumd(result,new Object[]{1,2,3});
            System.out.println(result[0]);
        }catch (Exception e){
            e.printStackTrace();
        }
    }
}

需要引用的jar包，javabuilder.jar在如下路径中找到

运行结果如下
