How can I write data repeatedly to an Excel file on a network drive from MATLAB R2024a?

I have a MATLAB script where I am using repeated calls to "writematrix" to write data to an Excel file on a network drive. The script will sometimes run successfully, but sometimes it fails at various lines with the following error.

Unable to write to file '...' You might not have write permissions or the file might be open by another application.

I am looking for a consistent approach to write all of my data to this Excel file.

Writing data to a file on a network drive can sometimes lead to inconsistent behavior, especially when repeatedly writing to the file in quick succession. Please ensure that the network connection is stable and that anti-virus or synchronization software is not interfering with the file. If inconsistent behavior persists, a more reliable approach would be to first write all of the data to a local file, and then copy the file over to your network drive at the end. Additionally, trying to minimize the number of calls you make to "writematrix" will also help to minimize error.
