I have made a Gui in labview which contain MATLAB script in it . Means it is opening a port in labview , doing some work and close port in labview after that goes into MATLAB script in labview and connect a port to MATLAB. It then Perform some function in MATLAB script and then again close a port inside script and exit it and again connect the port in labview and do some further processing. Now I want to build a app . What are the requirements for building an app of labview GUI that contains MATLAB script function inside it because it is calling something from MATLAB.
