Hi Olga,
Finally, I decided to execute my Matlab program siparatly from LABVIEW acquisition program.Since, when matlab P. is long, the time of calculation by matlab is so long as compared with the time required for LABVIEW execution. So, it is not possible to execute both deux program in the same espace of time.
But, if you have one syclic acquisition avec low frequence, it is possible!
