MATLAB 2018b readtable error after update

122 views (last 30 days)
Have a script using
readtable
to read from a .csv file.
Worked fine before a MATLAB update but now no matter how I use readtable, I get this error:
Error using readtable (line 216)
An error occurred while trying to determine whether "readData" is a function name.
How can I fix this? Thanks

I got a different error when using:
readtable('file.csv')
Error using readtable (line 216)
Delimiter must be a string array, character vector, or cell array of character vectors.
Note: readtable detected the following parameters:
'Delimiter', ',', 'HeaderLines', , 'ReadVariableNames', true, 'Format', ''
I also uninstalled and reinstalled R2018b, and 'readtable' seems to be working now.

Thanks all for the suggestions. I reinstalled MATLAB 2018b today and that fixed the problem. Going to stay away from the update button.

This is an installation issue. Although this might not resolve the issue try
>> restoredefaultpath
>> rehash toolboxcache
You can check
>> which readData -all
The correct version for readtable is ...matlab/toolbox/shared/io/+matlab/+io/+internal/+text/TableParser.m
If there's something else, then try temporarily renaming the others or removing their folders from the path.
If this still doesn't work you might need help from tech support.

I had a readtable error involving " too many arguments" and this worked for me
