Arrays of Time Series Objects Supported
MATLAB now enables you to create arrays of timeseries objects. In Version 7.10
(R2010a) and before, timeseries objects behaved as arrays, but some array behavior
was overridden.
Compatibility Considerations
Note: It is likely that this change is important to you only if you write code that uses
timeseries objects.
In Version 7.11 (R2010b), all of the overridden behaviors for the functions listed in
the table that follows are removed. The behavior of these functions on timeseries
objects is the built-in behavior for arrays of objects. Think of a timeseries object as
a single object that you can concatenate into an array of objects. Do not think of each
timeseries itself as an array.
