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 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.
