Greetings izna,

Please provide more information, such as:

What does the CSV file look like?
What does MATLAB want to read?
What commands are you using for loading into MATLAB?
Have you tried the "easy importer" feature that MATLAB provides?

2. Select Spreadsheet Data Using Import Tool: http://www.mathworks.com/help/matlab...ractively.html

Best regards,
Bruno

Hi Izna,

Try the instructions given on the list item #4. In addition, near the easy data importer, there is also the easy plot tool.
Sorry, I don't know their specific names, but they are mentioned in the links on my previous post.

As for the data, a quick look at the image, and I can't find anything wrong with it. You should be able to import the data to MATLAB.

Best regards,
Bruno
