Mat4J
MATLAB Engine for Java
This library uses the C API of the MATLAB Engine to:
- put variables from Java to Matlab
- evaluate Matlab commands
- get results from Matlab to Java
Simple Example
This Java code:
MatlabEngine matlabEngine = new MatlabEngine();
matlabEngine.open(null);
matlabEngine.eval("x = sin([0:pi/2:2*pi])");
System.out.println(matlabEngine.getOutput());
DoubleMatrix doubleMatrix = (DoubleMatrix)matlabEngine.getVariable("x");
System.out.println("doubleMatrix = " + doubleMatrix.toString());
matlabEngine.close();
Prints the following to standard output:
x =
0 1.0000 0.0000 -1.0000 -0.0000
doubleMatrix = [[0.0, 1.0, 1.2246467991473532E-16, -1.0, -2.4492935982947064E-16]]
Please have a look at the unit tests in the src package for more examples.
Test Console
mat4j.sh / mat4j.bat is a Java console application for evaluating Matlab commands.
Predefined Java commands:
exit / quit - Quits this application
get varname - Converts Matlab variables to Java objects and calls toString()
getImage hFigureVarName - Grabs a Matlab figure to a Java AWT Image
Example:
>> x = [1:5];
>> get x
[[1.0, 2.0, 3.0, 4.0, 5.0]]
>> x
x =
1 2 3 4 5
