Vertical concatenation for tscollection objects
tsc = vertcat(tsc1,tsc2,...)
tsc = vertcat(tsc1,tsc2,...)
performs
tsc = [tsc1;tsc2;...]
This operation appends tscollection objects.
The time vectors must not overlap. The last time in tsc1 must be earlier
than the first time in tsc2. All tscollection objects
to be concatenated must have the same timeseries members.
