Package: dsp
Find mean value of input or sequence of inputs
The Mean
object finds the mean of an input
or sequence of inputs.
To compute the mean of an input or sequence of inputs:
Define and set up your System object™. See Construction.
Call step
to compute the mean according to the
properties of dsp.Mean
. The behavior of step
is
specific to each object in the toolbox.
H = dsp.Mean
returns
an object, H
, that computes the mean of an input
or a sequence of inputs.
H = dsp.Mean('
returns
a meanfinding object, PropertyName
',PropertyValue
,...)H
, with each specified property
set to the specified value.

Calculate over single input or multiple inputs When you set this property to 

Additional input to enable resetting of running mean Set this property to 

Condition that triggers resetting of running mean Specify the event that resets the running maximum as one of
 

Dimension to operate along Specify how the mean calculation is performed over the data
as one of  

Numerical dimension to calculate over Specify the integer dimension, indexed from one, of the input
signal over which the object calculates the mean. The value cannot
exceed the number of dimensions in the input signal. This property
only applies when you set the 
clone  Create mean object with same property values 
getNumInputs  Number of expected inputs to step method 
getNumOutputs  Number of outputs of step method 
isLocked  Locked status for input attributes and nontunable properties 
release  Allow property value and input characteristics changes 
reset  Reset internal states of meanfinding object 
step  Mean value 
Compute the mean of a signal:
hmean1 = dsp.Mean; x = randn(100,1); y = step(hmean1, x);
Compute the running mean of a signal:
hmean2 = dsp.Mean; hmean2.RunningMean = true; x = randn(100,1); y = step(hmean2, x); % y(i) is the mean of all values in the vector x(1:i)
This object implements the algorithm, inputs, and outputs described on the Mean block reference page. The object properties correspond to the block parameters.
