How to import coordinates from a txt/csv file

Hi everyone,
I am very new to MATLAb so this is probably a very basic question. I am trying to write a script to analyse some results I have, I can output my results as either txt or csv files whichever works best. My issue is the file outputs the coordinates in the form (0,0,0) so I am not sure what the best way to import this would be if I wanted to create a 3D scatter plot, as the brackets seem to be causing problems.
Thanks for any help you can offer!

Something like this should read your data. Try
>> cac = cssm( )
cac =
[3x3 double]
>> cac{:}
ans =
1 2 3
4 5 6
7 8 9
where
function cac = cssm( )
fid = fopen( 'cssm.txt' );
cac = textscan(fid, '(%f%f%f)', 'CollectOutput', true ...
, 'Delimiter' , ',' );
fclose( fid );
end
and where cssm.txt contains (I'm guessing)
(1,2,3)
(4,5,6)
(7,8,9)

R2, where did you attach your data file? It's not really fair or helpful to make people who are trying to help you work "blind" by not providing them with your data file. http://www.mathworks.com/matlabcentral/answers/728-how-do-i-write-a-good-question-for-matlab-answers

A=dlmread('Yourfile.txt')
Or
A=xlsread('Yourfile.csv')
