the code ran without issues on Matlab 2018a. now i am switching to 2023B, and tried to run the code, but got the error message.
Unrecognized function or variable 'fetchmulti'.
I didn't find fetchmulti.m in 2023b folders. why is that? I assume everything has been installed automatically.
Thanks,
Jeremie

According to the documentation, fetchmulti was introduced in R2024b, and is part of the Database Toolbox.
If you were using it in R2018a, that version must be a function that you (or someone else) wrote.
