I want to know whether the Microsoft Access databases are not recognized by MATLAB R 2015b? I ran the Access database with MATLAB R 2009 and it worked well. What I have to do if I want to run the Access database with R 2015b.
one problem might be the version you have: could it be that your R2009a was 32 Bit whereas your R2015b is 64Bit? In this case it could be problematic to access the 32 Bit MS Access DB.
