best way in terms of performance to read a text file

I have to read values from text file that have this body:

1 2 3 4 5 6 7 8 9 10

after having read every of those value I would copy them in a vector. which is the best way in terms of speed and performance?

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?
