Hi guys,

I got alot of variables due to high amount of samples to analyze. I import csv data from the import tool and then process each variable that was imported.

I want to know, what is the recommended way to run code on several variables and then save the outputs in an ordered way? can you refer me to a page or video that can explain it?

tanks very much!

Amit.

hello

I would recommend you organize your data in a structure

then it's fairly easy to save the entire structure in a mat file

Hi Amit,

When you're working with a substantial number of variables in MATLAB, particularly from CSV file imports, adopting a systematic method involving loops, cell arrays, or structures for processing and organizing your data is advisable. This method aids in efficiently managing your data and ensures your code remains tidy and scalable.

Additionally, for handling large datasets, consider using Datastores. Datastores in MATLAB are designed to simplify the processing of large volumes of data. You can learn more about how to use Datastores by visiting the following documentation,

https://www.mathworks.com/help/matlab/datastore.html

Please explore each option to determine which best meets the needs of your dataset.

Hope this helps.

This seems a pretty reasonable answer, given the vagueness of the question. Sadly, it is several years beyond when the question was asked, so I've accepted the answer.
