MWMCR::EvaluateFunction error in ASP.NET - The specified procedure could not be found

I am getting the below error when trying to call my MATLAB function using the dll's provided by the Library compilier in ASP.NET:

... MWMCR::EvaluateFunction error ...

Loading C:\Program Files\MATLAB\R2021b\bin\win64\builtins\vision_builtins\mwvision_builtinimpl.dllfailed with error: The specified procedure could not be found. : state not recoverable: state not recoverable.

My MATLAB function uses bagOfFeatures and the NN predict function.

Any advice would be great.

Hi Chloe,

A possible cause for the error you are getting is a dll conflict. Please go through the following pointers:

• Generally ASP.NET is loaded by IIS, which also has a specific DLL search order.
• Therefore the DLL version of your compiled MATLAB function does not work because of a DLL conflict issue with IIS.

Thanks.
