Thanks Guys,
I used the option of creating the random numbers with C++ directly, rather than 
using octave to create it and importing  to deal.ii. Its running ok now.
Thanks very much.

Subject: Re: [deal.II] Importing a file

Hi Ricky,

A quick google search with the terms "c++, read data from file" might reveal 
the information you're looking for. Perhaps this website has the answer:
http://www.bgsu.edu/departments/compsci/docs/read.html
If you're reading data that is all numeric, then you simply pass the 
information from the ifstream to a variable of type "double" and go on your 
way. Of course, if you are dealing with point and value data then you'd have to 
parse the read-in information yourself.

An alternative, if I may suggest, is to generate the random numbers using the 
rand() function in the <cstdlib> library:

It is possible to bound the values generated by the function. You could also 
seed the generation of the numbers (using srand()  ) so that, although it 
appears that truely random numbers are generated, you can produce the same set 
of numbers at will at any occasion.

J-P
