Matlab-Java Integration, Working note.

Since Matlab runs on a JVM, it can easily integrate JAVA classes. Here is a quick view, mostly taken from the Matlab documentation.

 
[mFns, mexFns, javaClasses] = inmem; %Check which classes in memory

% classpath 
which classpath.txt
edit classpath.txt 

% imports
import java.lang.String
L = import % return import list 

% creating objects
strObj = javaObject('java.lang.String', 'Hello World')
frame = java.awt.Frame('Frame A') 
setSize(frame, 800, 400)
newFrameRef = frame

% concatenating object using cat or [] 
myObjs = [strObj; frame] 

% save trial.mat myObjs 
% load trial.mat 

% getting class attributes
names = fieldnames(strObj, '-full') % second argument optional 

% accessing object data
frameDim = getSize(frame) 
h = frameDim.height 

w = java.awt.Frame.WIDTH % static data, say, counters

% test class name
if (isjava(obj))
    name = isa(obj, 'class_name')
end

% invoking methods
% obj.method(args) OR method(obj, args) 
getTitle(frame) 
javaMethod('startsWith' , gAddress, str) % longer method names
java.lang.Double.isNaN(2.2) % static methods
javaMethod('isNaN' , 'java.lang.Double', 2.2) % static javaMethod 

methodsview java.awt.Frame % class name 

javaArray('java.lang.Double', 4, 5)
