Timeseries can't be subscripted in R2012a?

I'm transitioning from R2009b to R2012a.

In R2009b I was able to extract samples from a timeseries by subscript. For example

t=(0:0.01:2)';
ts=timeseries(sin(2*pi*t), t);
plot(ts(1:100))

This would plot the first half of the timeseries.

In R2012a, this code causes the error message "Index exceeds matrix dimensions."

The function timeseries/subsref.m seems to be missing from R2012a... there was no message that it's usage is deprecated or anything.

Is this a known problem? any workaround (hopefully without rewriting existing code?)

Thanks

In R2012b, ts is a 1x1 scalar object, you'll have to access its properties directly:

plot(ts.Time(1:100),ts.Data(1:100))

Can I ask that this change of behavior be documented?

Hi Adee, I would guess this is the change that did it (R2010b)
