I need to import data as a cell array to Matlab for many files and later perform some operations to them. Is there any way I can import the data in a script to do it automatically instead of manually?
What I do manually is:
-Home > Import Data
-Choose .txt file
-As a cell array, 2 columns as text.
-Column delimiters: comma.
Thank you

Zynk, in the import tool, after you make your selections, there's an option to "Generate function". You could then use this function on all of your files by looping over the filenames.

You do not give the actual file format or the file itself, so I cannot provide exact code. I would use the textscan function.
A possible (untested) way to code it would be:
fidi = fopen( filename );
data = textscan(fidi, '%f%f', 'Delimiter',',');
Be sure to explore the other name-value pair arguments if necessary.

The ‘table’ functions are a more efficient solution, but they were introduced with R2013a, and not everyone has access to them. Unless I know the version people are using, I go with the most generic solution possible.

My final objective was to get a structure-type variable, so I found this solution:
file= readtable('file.txt','Delimiter',',');
result=table2struct(file);
