Details:

The internal reconstruction of the time vector with  dt = t(2) - t(1);  and  t
= reshape (tinitial : dt : tfinal, [], 1);  can be susceptible to round-off,
rising unjustified complaints about size inconsistencies between U and T. The
attempted fix gives prime importance to the  len_t  variable, instead of  dt 
. On the fly, some other cosmetics are suggested, also in the help text.
