I get the following error when I am calling

readtable('file.csv')
Error using readtable (line 197)
An error occurred while trying to determine whether "readData" is a function name.
Note: readtable detected the following parameters:
'Delimiter', ',', 'HeaderLines', , 'Format', ''

Can you please help me on this one (do not provide me links on the same topic, I have checked everything and nothing is working) ?

hi

maybe you should share a copy of your csv file to let us check the issue

Hi Sokratis,

The error you are encountering with "readtable" in MATLAB could be due to several reasons. You may consider the following steps:

Ensure that the file path is correct and the file exists at the specified location.

filePath = 'file.csv';
if exist(filePath, 'file') ~= 2
    error('File does not exist at the specified path.');
end

Sometimes, MATLAB's path can get corrupted. Resetting it to the default state can help.

restoredefaultpath;
rehash toolboxcache;

Try specifying the delimiter and other parameters explicitly in the "readtable" function.

opts = detectImportOptions('file.csv', 'Delimiter', ',');
T = readtable('file.csv', opts);

Ensure that the file content is properly formatted and does not contain any unexpected characters or missing values that could cause issues.
Clear any functions and variables that might be interfering with "readtable".
If "readtable" continues to fail, try using "readmatrix" or "readcell" as alternatives to read the data.

I hope this helps!

Thank you.
