HANtune can be interfaced with MATLAB® (and by extension Simulink®). We can do this by using the MATLAB engine and calling it from a script.
Note: You will need to have installed a version of MATLAB® with the Java MATLAB engine.

Connecting to the MATLAB Engine
Reading data from a running Simulink model
Set your model
#Change these to the name and location of your model modelName = 'MyModel' modelPath = 'C:\Users\Michiel Klifman\Desktop'
#Add folders to MATLAB path
from java.lang import System
scriptPath = System.getProperty("user.dir") + "\scripts\examples\MATLAB_Interface"
engine.eval("addpath('" + scriptPath + "')")
engine.eval("addpath('" + modelPath + "')")
Creating a daq list
#Create a daqlist from signals in the model result = engine.feval(2, 'createDaqList', modelName, 'signals') daqItemNames = result[0] daqList = result[1] daqSize = len(daqList)
#Create a signal for each item in the daq list signals = [] removeAllSignals() for name in daqItemNames: signal = createSignal(name) signals.append(signal) updateLayout() print 'DAQ list created with ' + str(daqSize) + ' items'
