str2num

[lad]

Dear All

I am trying import some data into octave. I have a strange problem in
doing that. I can not get the str2num to work as I think it should work.

I read my data from a file with fgets (whic returns a string) and the I
would like to change the string to numbers.

look at the following minimal example wich reproduce my error:

> x="123456"
x = 123456

> ischar(x)
ans = 1

> y=str2num(x)
y = [](0x0)

I the last intry i would have expected a number or matrix.
What am i doing wrong here?

I use Ocatve workshop on win XP (and Me).

Best

Lars
