The textscan function using a numeric format descriptor string will automatically stop when it encounters:
*Element, type=C3D4
so this is actually a straightforward problem:
fidi = fopen('Copy_of_Job-1.txt','rt');
D = textscan(fidi, '%f%f%f%f', 'HeaderLines',9, 'Delimiter',',', 'CollectOutput',1);
with ‘D’ being a (1418x4) double matrix.


I am not certain what you are asking. I believe the code I posted in my Comment will do what you want.
If your file format remains the same, my code will work with all your files.

As always, my pleasure.
