System object: dsp.ArrayVectorMultiplier
Package: dsp
Multiply array by vector
Y = step(avm,A,V)
Y = step(avm,A)
Note
Starting in R2016b, instead of using the step method
to perform the operation defined by the System object™, you can
call the object with arguments, as if it were a function. For example, y
= step(obj,x) and y = obj(x) perform
equivalent operations.
Y = step(avm,A,V) returns Y , the result of multiplying the input
array A by the elements of input
vector V along the specified dimension
when the VectorSource property is Input
port. The length of the input V
must equal the length of the specified dimension of A.
Y = step(avm,A) returns Y , the result of multiplying the input
array A by the elements of vector
specified in Vector property along the specified
dimension when the VectorSource property is set to Property.
The length of the vector specified in Vector property
must equal the length of the specified dimension of A.
Note
obj specifies the System object on
which to run this step method.
The object performs an initialization the first time the step method
is executed. This initialization locks nontunable
properties and input specifications, such as dimensions, complexity,
and data type of the input data. If you change a nontunable property
or an input specification, the System object issues an error.
To change nontunable properties or inputs, you must first call the release method
to unlock the object.
