As for passing parameters between Matlab and python, we have an ugly=20 solution only: we save Matlab variables in a mat file which are then=20 read from the python script. In order to get the results back to Matlab,=20 we use text files. While this is not an optimal way of passing=20 parameters (maybe the upcoming Matlab version will reduce that pain, as=20 Stephan already mentioned), at least it works for us at the moment. Maybe that helps you. Best regards, Piotr Alain de Cheveigne wrote: > Hi Marek, > > I am looking for the opposite: an easy, efficient and reliable way to = call Python from Matlab.
