Dear SPMers,
here are some news about my problems :
I was surprised because the new PC solution (Linux - Matab6 with Pentium 866
and 256 Mo RAM) had problem for realignment, but not our old Sun.
I have finally obtained the "old" Matlab 5.3 for Linux and it works very
well and fast !
So it seems that there is a problem with Matlab6 (at least with Linux and
some configuration).
Maybe you will be happy to know it if you are trying to use the new matlab
release...
and maybe you have suggestion to explain these differences ?
Thank you
