Error Using Determinant Function

Upon attempting to use Matlab's built in command to find the determinant of a matrix, I received the following error message.
Error using det LAPACK loading error: mkl.dll: The parameter is incorrect.
This was quite puzzling as I was simply trying to take the determinant of a 3x3 matrix, almost identical to the one given in the example of how to correctly use the det command. I cannot find anything anywhere to explain why you would get this LAPACK error. Any help is appreciated.

By default, MATLAB should be using Intel MKL for all linear algebra operations. Your MKL library should be located at matlabroot\bin\arch\mkl.dll.
You can try the following as a potential fix:-
- Verify that the file "mkl.dll" exists in matlabroot\bin\arch, where matlabroot is your root folder, and arch corresponds with the architecture of your system.
- Set the values of both the LAPACK_VERSION and BLAS_VERSION environment variables to "mkl.dll" (without the quotation marks).
- Restart MATLAB and see if you still experience those errors.
