Calling Sequence

MovingAverage( A, n )

Parameters

A

-

Array of real numeric values; the signal

n

-

posint, size of the moving average filter

Options

• 

container : Array, predefined Array for holding results

Description

• 

The MovingAverage( A, n ) command applies a moving average filter of length n to a signal sample A, and returns its result as an Array with datatype float[8] of length numelems(A) - n.

• 

Before the code performing the computation runs, A is converted to datatype float[8] if it does not have that datatype already. For this reason, it is most efficient if A has this datatype beforehand.

• 

If the container=C option is provided, then the results are put into C and C is returned. In that case, the container C must have datatype float[8] and size numelems( A ) - n.

Thread Safety

• 

The SignalProcessing[MovingAverage] command is thread-safe as of Maple 18.
