Java calls MATLAB drawing

Environment:

System: Kali Linux 2017

java:1.8

matlab:r2016b

idea:2016

1. Write the Matlab script:

Drawplot.m

    % Paint Custom Function Drawplot parameter x y function      drawplot (x, y)        plot (x, y); percent percent use MATLAB function plot () Graph        grid on% grid display      Xlabel (' X-axis value ')      ylabel (' Y-axis value ')      title (' Java calls matlab graphing example ')  

Script saved to the specified folder

In the MATLAB command window:

>> Deploytool

Select Liberary Compiler

Type:java Package

Exported: Select DRAWPLOT.M

Modify the class name to: Plotter

Click Package

The folder below will be more than the project, there are we want to use the jar (Xxx.jar)

New project under Idea: Javamatlab

There are two dependent packages under the Libs folder:

---xxx.jar

---javabuilder,jar (in MATLAB installation directory \toolbox\javabuilder\jar\jarbuilder.jar)

Attention:

Select Edit Configurations

Add a Run environment parameter

Ld_library_path=/opt/matlab/runtime/glnxa64

Otherwise you will get an error: Cannot link to libmwmclmcrrt.so.9.1

The configuration is complete and functioning properly.
