Yes, you can try tfrrmsc() which computes the
Morlet Scalogram (alongwith its reassigned version)
using a different computing scheme than tfrscalo.m
that may work better with long duration signals.

If you are not interested in reassignment, you may
edit the m-file a bit to remove its computation
from tfrrmsc.m.

Note that the frequency/scale grid used in tfrrmsc()
is different and that you have to use Morlet wavelet.
