first call of inv() does not work

[Sebastian Schenker]

Hi everyone!

I have the following problem: After starting octave everything works
fine. Except the first call of the function inv or inverse. It doesn't
produce any output. To explain it in more detail.  After starting octave
I declare a matrix like B = [1 2;0 1] (for example).


When I know enter inv(B) as the next command nothing happens. No output
is produced but also no error message. Octave runs with about 90% of cpu
usage but does not finish. When I quit with Ctrl-c and immediately enter
inv(B) again the result (ans =1 -2 ; 0 1) is shown immediately. Now I
can also enter other (regular) matrices and inv() produces the results.

It only happens with the first call of inv in an octave session. Could
this be a bug or am I doing something wrong?


(There seem to be no other problem with octave. I am using gentoo linux.)


Does anyone have a clue?

best regards,
