Connecting a Matlab function to Modelica

Hello All,

I am trying to connect dynamically a MATLAB function to a Modelica Model.

This Matlab function I created is based on the MATLAB function lsqnonlin.

This function has to be called by Modelica everytime I run the model as it is used to obtain initial values.

Basically, what I want to obtain is something like this:

1) Run the simulation

2) Modelica sends the input value to Matlab

3) Matlab calculates a vector of outputs using lsqnonlin

4) Matlab sends these values to Modelica to initialize the simulation values

5) Start the simulation in Modelica

What I really want to obtain are points 3 to 5 (i.e. I can set manually the input value in Matlab before running the simulation in Modelica)

Do you know if there is a way to do this?

Thank you so much in advance!

Gabriele

Were you able to do it? I am stuck on a similar problem.

You can store values in a mat file and that can be used to communicate between MATLAB and Modelica.The part of the question - " I can set manually the input value in Matlab" is not clear.
