Details:

Right now lsode() works only in double precision (regardless of initial data)
and uses: libcruft/odepack/dlsode.f

An example:

>> y=lsode(@(y_) y_*(1-y_), single(0.1), t=single(linspace(0,10)));
>> class(y)
ans = double


There is already single precision FORTRAN code (libcruft/odepack/slsode.f),
but it's not used.
