I have a csv with a bunch of variables.
I want matlab to open the CSV, and put the first variable into one field, the second variable into the next field, etc.
How can I do this?
My csv file is actually a text file, test_file.txt Which contains: 1,120,5e-05,000035,5,1000000,2425,102e-05,1,2,3,4,1e-15,15,0,32
So I want Matlab to put 1, 120, etc into the various fields I have in the GUI.
Thank you for your help and time.

The following code should work:
% Open CSV file
fid = fopen('myCSV.txt', 'r');
% Read comma-separated values
A = fscanf(fid, '%f,');
% Don't forget to close the file
fclose(fid);
All your values will be stored in the vector A. You can then access them by calling A(1), A(2), A(3), etc...
Note that values have to be written in the text file like you said ("value1,value2,value3"); otherwise, it won't read them correctly. Let me know if you have more questions.

Yes, put it in the callback for the submit button, if that is where you thing the best place to read in the file is. If you have a uitable and want to display the data in the grid/table control, then pass Bruno's "A" into set():
set(handles.uitable1, 'Data', A);
