C1189 #error: Using MATLAB Data API with C Matrix API is not supported.
显示 更早的评论
Hey,
I am trying to replicate this tutorial with Matlab R2025a, UE 5.32 and Visual Studio 2022. I am getting the following error in Visual Studio at step 6, when I click "build".
C1189 #error: Using MATLAB Data API with C Matrix API is not supported.
I saw some previous posts discussing the same issue and the solution was the update to a new release. However, I have the latest release.
Best,
Filippos

The suggested fix worked for me too in a similar use case.

Hi Filippos,
Thank you for reaching out about this error! It is unfortunate that this has been a recurring issue as we update the product from release to release, but the development team is trying to investigate the deeper underlying issue and hopefully implement a more lasting fix in a future release.
For now, in R2025a, the following workaround might help resolve this error:
In the following file that we install with our plugin: C:\Program Files\Epic Games\UE_5.3\Engine\Plugins\Marketplace\MathWorks\MathWorksSimulation\Source\MathWorksSimulation\Public\Sim3dInterface.h
Please replace line 7
#include "Engine.h"
with the following instead:
#include "Engine/Engine.h"
Please let me know if this resolves the error for you. If it doesn't, we'd be happy to investigate it more.
Thanks,
Nishan
