Does the Digilent Toolbox Add-On work with Matlab Library Compiler?

Does the Digilent Toolbox work with the Matlab Library compiler? I'm attempting to deploy a matlab .NET application, but when the deployed application runs the command

AO = daq("digilent")

it returns the exception "Specify an operational vendor" which tells me it doesn't have the Digilent Toolbox info included in the compiled application.

I also don't see Digilent Toolbox in the Suggested Support Packages in the Library Compiler application window.

Here is a link to the toolbox I'm referring to: https://www.mathworks.com/matlabcentral/fileexchange/122817-digilent-toolbox

If the question pertains to whether the Digilent toolbox itself can be compiled using the MATLAB Library Compiler, then we unfortunately cannot do it because it is an add-on to MATLAB that provides additional functionality and not a standalone due to which it cannot be compiled on its own.

If you plan to encompass the Digilent Toolbox functions in your MATLAB code, and then compile that code using the MATLAB Compiler, then yes, it is possible. However, you would need to ensure that the Digilent Toolbox is installed on the target machine where the compiled application will run.

Hi Vinayak, thanks for the response. See the code shown below. My problem is that "digilent" is not recognized as a daq option on the target machine specifically when this line of code is run:

AO = daq("digilent"); % DAQ session for the AWG channel

I installed MATLAB runtime on the target machine, and everything else seems to be working as expected. How do I ensure that the Digilent Toolbox is installed on the target machine? I was assuming it would be included when compiled, but this appears not to be the case...?
