If your text file has exactly what you've got there (numbers separated by spaces):
---== contents of test.txt ==---
1 2 3 4 5 6 7 8 9 10
--------------------------------
Then just use importdata
A = importdata(filename)
A =
1 2 3 4 5 6 7 8 9 10
Quick, simple. MATLAB will be pretty optimised to read this kind of file. Is that what you were looking for?
