I am using octave-0.71.1 installed with gcc-2.3.3 on sun
expm doesn't work correctly.
I add two examples of expm strange results.
For simple matrix like a=[1,2;3,4],
the correct answer is given by expm(a);
The trouble seems to be occured when the Jordan form of the
matrix is not diagnal.
Is the trouble caused by my installation or a bug of octave?
I am looking forward to getting reply.
I am sorry I sent a mail without my name or address.
