Last value of Moving Average in single command

Hi,

I have A = rand(10,1). I am calculating an exponential moving average, B = movavg(A,'exponential',2). I only want the last value of B, i.e. C = B(end).

Is there any way to do this in a single command?

Thank you!

Here's a way:

A = rand(10,1);

% original, for reference:
B = movavg(A,'exponential',2);
C = B(end) 

C = 0.8873

% single-line command:
C = subsref(movavg(A,'exponential',2),substruct('()',{numel(A)}))

C = 0.8873

Thank you for showing me the subsref command!
