Issue Details

I have MATLAB® code written by someone else and I want to integrate this into the LabVIEW code I am writing, but I do not have access to a MATLAB® license. What are my options for integration?

Solution

You will have to create compiled code in MATLAB® and use LabVIEW to call the compiled code, instead of using LabVIEW to directly connect to the MATLAB® script server. For example:

Create a shared component, i.e. DLL, in MATLAB® and call the DLL from LabVIEW using the Call Library Function Node. Note that the input and output data types of the DLL must be C data types in order to work correctly in LabVIEW. The article Using DLLs Built with MATLAB Coder in LabVIEW shows a way to achieve this.
Create a .exe file in MATLAB® and run it from LabVIEW using the information contained in How Do I Run an Executable or External File from within LabVIEW?

Additional Information

The use of the LabVIEW MATLAB Script Node and LabVIEW MATLAB® functions require a valid MATLAB® license. If a computer without a MATLAB® license needs to run MATLAB® code using LabVIEW, then use the above options.
