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!

Ran in:
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
