Error Message:
I have a script using readtable('data.csv') running on MATLAB 2024a that is producing this error if I modify my path from the MATLAB default (set by restoredefaultpath):
Error using readtable (line 517)
inputs must be a string array, character vector, or cell array of character vectors.
Trouble Shooting I've Tried:
If I run restoredefaultpath and then execute T = readtable('data.csv') it runs OK.
T = readtable('data.csv')
It seems like MATLAB can find readtable.m but cannot find readData.m:
which readTable -all` returns C:\Program Files\MATLAB\R2024a\toolbox\matlab\iofun\readtable.m
and
which readData -all returns 'readdata' not found
both with the default path and my modified path.
I've tried uninstalling and then reinstalling MATLAB 2024a to no sucess.
Requested Help:
However, I need to be able to modify my path so that my script can access the m-files it needs. What can I do to fix this problem? Thank you for your help!

That's odd, since clearly the inputs are a cell array of character vectors. The problem must be inside the unescape function.
Good work in tracing it down this far!

Please attempt to reproduce this failure on your machine. If you can, immediately (before running any other command that could throw an error) run the following line of code at the MATLAB Command Prompt (the >>) and show what it displays (and if you could save the variable ME and attach the MAT-file containing it to the post that would be useful too.)
ME = MException.last
The identifier property may help indicate what function caused that error.
My suspicion is that you've written your own string processing function (strcmpi perhaps) or downloaded one that shadows a function built into MATLAB or that ships with it. The lower-case I starting the error message is a bit of evidence that supports that suspicion.

Glad we were able to track down the root cause of that error!
