Example of timeseries Object Concatenation

Suppose you concatenate the following two timeseries objects:

t1 = timeseries(ones(5,1),0:4);

t2 = timeseries(zeros(5,1),5:9);

In R2010a, the following syntax created a single timeseries object, t3, with 10 samples

spanning the time range 0-9. The first 5 samples derived from t1 and the last 5 samples

derived from t2. The size of the timeseries, t3, was [10 1] and its length was 10,

because t3 has 10 samples.

t3 = [t1;t2]

t3 = vertcat(t1,t2)

Now, the same syntax creates a 2x1 array comprising the two timeseries objects t1

and t2. Its size is [2 1], and its length is 2 because the array has two rows, each a

single timeseries.
