converting decimal string to a number

[StevenHowell]

CSV is a Comma Separate Value, its a format type for text file. Typically a CSV file can be opened in a spreadsheet, as its delimeter is a "comma" or a "tab", either way, it is a text file. I am not too familiar with Matlab, but you would basically open the CSV (txt) file using whatever commands you use in Matlab to open files. Typically a file name will be something like "mydata.csv" 

Does this make sense?

Good afternoon. I wonder how to implement a low pass filter on my system. Which icon to use and where to put. Thank you.

This seems completely unrelated to the current discussion, so please start a new thread.

Also explain your "system". Is this a hardware or a software questions?
